The calorimeter contains 1.00 kg of water (CH2O = 4.184 J/g C) and the heat capacity of the empty calorimeter is 0.10 kJ/C. How much heat is released per gram of oil shale when it is burned
A .100 M solution of a monoprotic weak acid has a pH of 3.00. What is the pka of this acid?
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base.
