Thus, we need to neutralize their toxicity before they can be thrown out. So if equal amounts of acid and alkali are mixed, the resulting solution will be neutral. 25) 25.00 ml of 0.0962 m hydrochloric acid is titrated with a calcium hydroxide solution, and 32.53 ml of the base is required for complete neutralization. This uses the scientific names for the acid and alkali placed on the reactant side of the equation. water 3. BBC KS3 Bitesize Science Acids bases and metals. (see the next page). Neutralization reactions are one type of chemical reaction that proceeds even if one reactant is not in the aqueous phase. Net neutralization reactions of ionic equations include solid bases, solid salts, water, and solid acids. Science Period 7 The sulfate ion SO 4 2- (aq) is called a spectator ion , because it doesn't change in the reaction and can be omitted from the ionic equation.
