It is a proton donor

Question 2

What is the equation for Kw, the equilibrium constant?

Answer 2

Kw=[H+(aq)]eqm [OH-(aq)]eqm

Question 3

What is the definition of a substances pH?

Answer 3

-log10[H+(aq)]

Question 4

How do you find [H+(aq)] from pH?

Answer 4

10^-pH

Question 5

How do we find [OH-(aq)] from pH?

Answer 5

First find the value for [H+(aq)] for example 10^-10. Take this away from 10^-14 to find the value for [OH-(aq)]. In this case it would be 10^-4
