Between 1751 and 1996, surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14, representing an increase of almost 30% in H+ ion concentration in the world's oceans. What phrase below best describes the above process. Group of answer choices Ocean acidification Pollution Water and soil acidity Feedback loop accelerating climate change

From the mid-1800s to the present, the average acidity of the oceans' surface water has increased $30 \%$ to its current $\mathrm{pH}$ of $8.1 .$ Calculate what the $\mathrm{pH}$ was in the mid-1800s.
Over the past 250 years, the average upper-ocean pH near the Pacific Northwest has decreased by about 0.1 units, from about 8.2 to $8.1 .$ This drop in pH corresponds to an increase in acidity of about $30 \%$. When $\mathrm{CO}_{2}$ levels in seawater rise, the availability of carbonate ion, $\mathrm{CO}_{3}^{2-},$ decreases. This makes it more difficult for marine organisms to build and maintain shells and other body parts from calcium carbonate. (a) Calculate $\mathrm{H}_{3} \mathrm{O}^{+}$ and $\mathrm{OH}^{-}$ concentrations at $\mathrm{pH}$ levels of 8.2 and 8.1. (b) Demonstrate by calculations that this decrease in $\mathrm{pH}$ corresponds to an increase in acidity of about $30 \%$. (c) Explain the relationship between the pH of seawater and the availability of carbonate ion. Does the change in pH from 8.2 to 8.1 result in an increase or decrease in the availability of carbonate ion?
Carbon dioxide released from burning of fossil fuels contributes to the acidity of the oceans' surface water, whose current average $\mathrm{pH}$ is $8.1 .$ It has been estimated that if $\mathrm{CO}_{2}$ emissions are not curbed, the oceans' surface water pH could drop to 7.8 by the end of this century. Calculate the percent change in acidity if that were to happen.
