1. You want to prepare 50cm cube of 0.1m NaOH frrom exactly 50%(wt/wt) NaOH solution. What volume of the 50% solution is required?
2, what is a primary standard? Can KOH be used as a primary standard? Explain.
3. An aqueous sample is analysed and found to contain 4% NaOH.
(i). Calculate the concentration of the molar concentration of the solution assuming the density of water is 1.00g/cm cube.
(ii). If the solution is neutralized with 1.0M H2SO4, what volume of the acid will be needed.?
