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.

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?

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.

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.

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).
