This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The Isthmus of Tehuantepec in Mexico is one of the windiest places on earth making it a hotspot for investment in wind energy. But that’s proving problematic. Because although wind-energy investments appear to be paving the way toward a sustainable future a new study reports that a lack of good governance is proving unsustainable for the large indigenous population that calls the Isthmus home. Mexico is among the many nations that have implemented policies supporting the Sustainable Development Goals established by the United Nations. a blueprint for achieving a sustainable future for our planet. But in the Isthmus of Tehuantepec, these efforts do not adequately include local indigenous communities. It’s a problem caused by a combination of corruption, poor accountability, and limited access to information about energy and the environment. Fortunately, paths for reversing these poor governance patterns do appear to exist..."

In this activity, students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also learn several things that engineers are doing to reduce the effects of acid rain.

Short video on the bicarbonate ion buffer system for acid-base balance for anatomy and physiology.

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

This activity is acid-base titration lab where students determine the percent of calcium carbonate in an eggshell.

In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create the final solution. Next, they prepare the solution using the appropriate glassware, and then can check their answer using the concentration viewer in the solution info panel.

In this field-based exercise, students were given a tour of an abandoned mine site and asked to utilize a set of field measurements to describe the spatial details of metal transport. This drew on previous experience with field measurements and prompted them to work together to solve an observed chemical evolution of a contaminated brook. The exercise is an excellent example for students to bring together acid-base chemistry, redox chemistry, and thermodynamic concepts together to describe a reasonably complex system. The field component was completed in a full day, but we will be expanding this next fall for a 2 day exercise (weekend). The exercise was coupled with subsequent labs to complete analysis of the water samples and accomplish speciation calculations using PHREEQCI.

Intended Audience: This activity was used for an introductory Geochemistry class, which contained students from sophomore level to master's students. We took the trip in mid-October, about as late as possible in Vermont, after they had gained some previous field experience and lab work in addition to an in introduction to these principles in class.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Cluster of questions on acid rain deposition.

This short video is an excerpt from the longer video Acid Test: The Global Challenge of Ocean Acidification, produced by the National Resources Defense Council (NRDC). This short version summarizes the science of ocean acidification as well as the social implications.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.

Produto educacional destinado, principalmente a pescadores artesanais e comunidades ligadas a pesca artesanal, contendo informações sobre espécies relacionadas a acidentes que envolvem animais aquáticos e pescadores artesanais, o perigo de determinados procedimentos inadequados e procedimentos recomendados como medidas de primeiros socorros.

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

Students research the acidification of freshwater streams and lakes, identify at least one of the sources, and determine how their daily activities contribute to the problem.

The most important property of carboxylic acids, an the one that is responsible for naming them such, is their acidity. An acid is any compound that donates a hydrogen ion (H+, also called a proton) to another compound, termed a base. Carboxylic acids to this much more readily than most other classes of organic compounds, so they are said to be stronger acids, even though they are much weaker than the most important mineral acids -- sulfuric acid (H2SO4), nitric acid (HNO3), and hydrochloric acid (HCl).

Learn about acids, bases and alkalis through engaging, bitesize animated videos. They are organised into these chapters: acids and bases, acid reactions, soluble salts, insoluble salts and uses of salts.

This module provides an intrioduction to acid and base chemistry. The Arrhenius and Bronsted-Lowry concepts of acids and bases are discussed as well as the pH scale and neutralization reactions.

In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.
