On Outline 2, the last bullet point (see below) states that we should be able to calculate the pH in particular examples. Do we have to memorize chemical formulas for these examples for the upcoming exam or can we expect to be given the reaction/chemical formula? Thank you!!

• Calculate the pH in these industrial, environmental, and biological examples: Carbon dioxide reacts with water to form carbonic acid, which makes carbonated drinks acidic, acidic rain, rivers, and lakes in the environment, and respiratory acidosis and death in biological systems.

I think it would be a good idea for you to memorize the chemical formula just in case! It's relatively straight forward.

I would recommend to at least get familiar with most of them.

I think that you would just want to know that CO2 when dissolved in water makes carbonic acid, which is H2CO3, which is responsible for all the environmental and biological examples listed in the outline below.
