Answer:

Explanation:

pH = - log[H⁺]

8 = - log[H⁺]

[H⁺] = 10⁻⁸

if this concentration of hydrogen ion increases to  100 times

New hydrogen ion concentration

[H⁺] = 10⁻⁸ x 10²

= 10⁻⁶

pH = - log[10⁻⁶]

= 6

new pH will be 6 .

Answer:

10

Explanation:

Because increased by a factor of 10 means that it moved two spots up the pH chart which each stage is wort 10. if it were to increase by a factor of 10 it would’ve been 9, it says increased by 100 so it’s 10.

Hope that made sense :)
