Question

Typical household bleach has a pH of 13. What is the H3O+ concentration in household bleach?

____× 10^n M n =____

Answer 1

1.0 and -13 is your answers

Answer 2

Answer:

The $H_3O^+$ concentration in household bleach is $1\times 10^{-13}M$.

Explanation:

The pH of the solution is defined as negative logarithm of $H_3O^+$ ions in the solution.

$pH=-\log[H_3O^+]$

Given the pH equal to the 13

$13=-\log[H_3O^+]$

$Antilog [-13]=[H_3O+]=1\times 10^{-13}M$

The $H_3O^+$ concentration in household bleach is $1\times 10^{-13}M$.
