Question

Chemists measure the acidity of an aqueous solution using pH. The pH is pH=-log-10[H^+] where pH is a measure of hydrogen ion concentration [H^+] measured in moles of hydrogen per liter of a solution. Find the pH of a solution if [H^+]=5.5x10^-12.

Answer 1

Answer:

11.26

Step-by-step explanation:

pH = - log(H+ concentration)

[H^+] = 5.5 * 10^(-12)

pH = - log(5.5*10^-12)

pH = - (-11.26)

pH = 11.26
