04 Question (10 points) Watch the Chem Tour animation below on acid-base titrations. Then, answer the questions about the following reaction: CaCl2(aq) + H2O(1) See section 8.5 An aqueous solution of Ca(OH)2with a concentration of 0.143 Mwas used to titrate 25.00 mL of aqueous HCI. 13.83 mL of the Ca(OH)2 was required to reach the endpoint of the titration. Ca(OH)2(aq) + 2HCl(aq) ACID-BASE TITRATIONS Introduction A titration is the sequential addition of reactant to a solution containing other reactants. In an acid-base titration, a basic solution of known concentration is added to an acidic solution of unknown concentration, or vice versa. The basic solution is added until the complete neutralization of the acid takes place. In this manner, the volume of the basic solution added will be used to determine the unknown concentration of the acid. O Real-World Connections א "mimimimimimil
