The charge of a nucleus is positive because protons are found inside the nucleus while electrons are on shells outside of it. there are three terms because of the different locations of the electrons and what they do. ex. shielding electrons shield the valence electrons from the strong pull of the nucleus

What is the concentration of H+ ions at a pH = 11?

natta225 [31]

Answer:

$\huge 1 × {10}^{-11} \: \: M$

Explanation:

The pH of a solution can be found by using the formula

$pH = - log [ {H}^{+} ]$

Since we are finding the H+ ions we find the antilog of the pH

So we have

$11 = - log({H}^{+}) \\ {H}^{+} = {10}^{ - 11}$

We have the final answer as

$1 × {10}^{-11} \: \: M$

Hope this helps you
