I have a Quan Chem problem. Please help me out!
A certain solution contains NaOH and Na2CO3. A 50.00 Ml aliquot of the mixed base requires 22.43ml of 0.1 N HCl to the Phenolphthalein endpoint. A second aliquot of the bases require 30.62ml to the methyl orange end point. Calculate the Normality of the NaOH in the original solution.
I actually confused about how to analyzed this type of problems. so please help me out. Thank you so much
