Extremes of pH can damage human tissues. Reflux is simply the effect of stomach acid damaging the esophagus. Several strong acids and bases can be found around the home. Lye is strong base used for a variety of purposes around a house. Lye can also damage tissues. What effect does lye have on pH ? A. Decrease pH B It does not change pH (C) Increase pH

You can also do the reverse, calculate the \( \mathrm{H}_{3} \mathrm{O}^{+} \)molarity from the pH , using the formula \( \mathrm{H}_{3} \mathrm{O}^{+} \)molarity \( =10^{-}-\mathrm{pH} \) What is the \( \mathrm{H}_{3} \mathrm{O}^{+} \)molarity of a solution having the pH of 2.56 ?
