You have been provided with a 0.1M aqueous solution of glycine at pH 9.0. Calculate how much (in ml) of 5M NaOH solution that you must add to 1 L of this 0.1M glycine solution in order to bring its pH to exactly 9.80
A reaction has a rate constant of 0.00704 sec-1, how long will it take (in minutes) until 0.212 mol/L of the compound is left, if there was 0.619 mol/L at the start
Neglect activity and assume that neither Hg2+ nor SCN- react significantly with water (no formation of HgOH+ or HSCN). Hint: you will probably want to make an assumption in the charge balance to simplify the problem and then test to see if the ass..
