Question

(1)What is active mass of water?
(2)What is the value of PKomega at 25°C
(3)What happens of the pH if a few drops of acid are added to CH3COONH4​

Answer 1

1. for water

density = 1g/ml

1000g/l

molar mass =18.015 g /mlol

so

1000 g/l = (1000 g/l)/(18.015 g/mol)

=55.51 mol/l

2. taking the negative of the pkw and raising it to tenth power can calculate the kw of watee at the given temperatures

3. ammomium acetate ch3coonh4 is a salt formed by weak acid and weak base
