A sample of 10.0 mL of HCI is neutralized using 22.1 mL of sodium hydroxide solution. Calculate the concentration of the HCI solution. sodium hydroxide 222.1 ml, Nal100

25 mL of chlorous acid is titrated with 0.5 M  magnesium hydroxide. Write out the chemical reaction when chlorous acid reacts with magnesium hydroxide.       2.How many molecules of chlorous acid are present if it requires 12.04 mL of magnesium hydroxide to reach the endpoint of the titration

A sample of oxalic acid (a diprotic acid of the formula H2C2O4) is dissolved in enough water to make 1.00 L of solution. A 100.0 mL sample of this solution is titrated with a solution of sodium hydroxide (NaOH) of concentration 0.750 M and requires 20.0 mL of sodium hydroxide to reach the end point. Calculate the mass of the original oxalic acid sample. H2C2O4 + 2NaOH → Na2(C2O4)+ 2H2O
