1. Calculate the molar mass of KHP . 2. Calculate the mass of NaOH required to prepare 400.0 mL , 1.0 M solution 3. Estimate the amount of 1.0 M NaOH (in ml ) required to neutralize 5.0 g of KHP 4. Given your previous experience with sodium hydroxide , why is it a good idea to standardize NaOH solutions , even if they were prepared using solid NaOH ? 5. How will you know when all of the acid has been neutralized by the sodium hydroxide 6. The concentration of a sulfuric acid solution isn't known , so it's titrated with an aqueous solution containing 3.00 g of sodium hydroxide . It took 22.8 mL of sulfuric acid solution to neutralize the base a) Write a balanced equation (with phases ) for the reaction that's taking place . b) How many moles of sodium hydroxide were present ? c) How many moles of sulfuric acid must have been present ? d) What is the concentration of the acid solution
