1. What is the pH of a solution made by combining 0.100 M C6H5COOH and 0.300 M sodium benzoate in water to make a 2.00 liter solution? (Ka = 6.3 X 10^-5) 2. Calculate the pH after adding 0.0200 liter of 1.00M nitric acid.
3. Calculate the pH after adding 0.0200 liter of 1.00M potassium hydroxide.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

it is the most commonly accepted one
