hey i actually just did this practical and got 10/15

Saida are the mole questions on finding out the unknown concentration of solution .....
What else questions are there on titrations apart from percentage error and procedural errors ....
Is the reaction with carboxyllic acid and sodium chloride ?
What is wrong with their experiment - procedural and how would you improve it
