Calculating pH Of Strong Bases

Question 1

What is Kw and it’s equation

Answer 1

Ionic product of water. Kw= [H+][OH-], H2O would be dividing by these but at any temp [H2O virtually constant

Question 2

Value for Kw

Answer 2

1 x 10^-14 mol^2dm^-6

Question 3

How to calculate pH of strong base

Answer 3

[H+]= Kw/[OH-]
Then -log[H+]= pH

Question 4

How to find pH of mixture of acid and alkali

Answer 4

Find which in excess, work out how many moles left after reaction then find concen by dividing by entire volume, then use this to find pH
