Chapter 9.6, Problem 9.11P

(a) What is the difference in ${\text{[H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}$ for each pair of solutions with the given pH values? (b) Which pH valueindicates the higher concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}?$
$\text{[1] pH = 4 and pH = 5}$
$\text{[2] pH = 4 and pH = 6}$
$\text{[3] pH = 6 and pH = 10}$
