4. To 43.4 mL of 0.221 M K2CrO4 solution are added 71.8 mL of 0.527 M ZnCrO4. Calculate the molar concentrations of each ion present in the combined solutions.
7. A 30.0 mL sample containing citric acid (H3C6H5O7), a triprotic acid, is titrated (neutralized quantitatively) with a solution of 0.106 M KOH. The titration requires 26.5 mL of the KOH solution. Calculate the molar concentration of the citric acid solution. Also, identify the salt formed in the reaction and calculate its molar concentration. Assume solution volumes are additive.
Please help and explain the process to solving. I'm so confused, thanks in advance! :)
