What is the [H+] if the pH of a
solution is 1.65?
[H+] = [ ? ]

The [H+] is 0,022M

Explanation:

The pH (hydrogen potential) indicates the amount of H + ions in a solution, it gives us an idea of how acidic or alkaline it is. It is calculated as                    pH = -log (H +). To calculate the H + concentration we perform this calculation:

(H +) = antilog -pH = antilog -1.65= 0,022 M
