Calculate the concentration of h3o⁺ in a solution that contains 5.5 × 10-5 m oh⁻ at 25°c. Identify the solution as acidic
Andreas93 [3]

Answer: [H_3O^+]=1.6\times 10^{-10}M , the solution is basic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.Neutral substances have pH of 7.

pH=-\log [H_3O^+]

pOH=-\log[OH^-]

Putting in the values:

pOH=-\log[5.5\times 10^{-5}]

pOH=4.2

pH+pOH=14

pH=(14-pOH)=(14-4.2)=9.8

9.8=-\log [H_3O^+]

[H_3O^+]=1.6\times 10^{-10}M

As pH is more than 7, the solution is basic
