Chapter 10: Acids and Bases and Equilibrium

Why would the pH of your blood plasma decrease if you hold your breath?

Someone with kidney failure excretes urine with large amounts of${\mathrm{HCO}}_3^{-}$. How would this loss of ${\mathrm{HCO}}_3^{-}$affect the $\mathrm{pH}$of the blood plasma?

Someone with severe diabetes obtains energy by the breakdown of fats, which produce large amounts of acidic substances. How would this affect the $pH$of the blood plasma?

At rest, the $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$of the stomach fluid is $2.0\times {10}^{-4}\mathrm{M}$. What is the$\mathrm{pH}$ of the stomach fluid?

At rest, the $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$of the stomach fluid is $2.0\times {10}^{-4}\mathrm{M}$̣ What is the pH of the stomach fluid.

When food enters the stomach,$\mathrm{HCl}$ is released and the $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$ of the stomach fluid rises to $4\times {10}^{-2}\mathrm{M}$. What is the $\mathrm{pH}$ of the stomach fluid?

In Larry's esophageal pH test, a pH value of 3.60 was recorded in the esophagus. What is the $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$in his esophagus?

In Larry's esophagal pH test, a pH value of 3.60 was recorded in the esophagus. What is the$\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$ in his esophagus?

After Larry had taken Nexium for 4 weeks, the $\mathrm{pH}$in his stomach was raised to 4.52. What is the $\left[{\mathrm{H}}_3{\mathrm{O}}^{+}\right]$in his stomach?

Write the balanced chemical equation for the neutralization reaction of stomach acid HCL with $CaC{O}_3$an ingredient in some antacids.
