at 20 degrees Celsius, the water ionization is 6.8x10^-15. What is the h3o concentration in nuetral water at this temperature? Explain in words.

1. What do you mean by 'typical ammonium salt'? There are so many ammonium salts that can be made...

2. You are given the constant of ionisation of water at that temperature. Work out the concentration of H_3O using the Kw expression.

2H_2O (l) \rightleftharpoons H_3O^+(aq)+ OH^-(aq)

K_w = [H_3O^+][OH^-] = 6.8\times 10^{-15}

From the equation, the same number of moles of H_3O+ and OH- are produced, this means;

[x][x] = 6.8\times 10^{-15}

where I call x the number of moles of products.

Solve for x.

Then, put it in your own words.
