Reaction is a neutralization reaction where water + salt is formed when a base (Ca(OH)2) and acid (H3PO4) react.
Neutralization reaction is a type of a double displacement reaction where ions are switched with their respective counter ions.
Part B. When the following reaction occurs:
H3PO4(aq) + Ca(OH)2(aq) →
What is the formula for the salt formed?
Express your answer as a chemical formula.
Reactions in water solution can be classified based on the driving force that converts reactants to product. The three classes are precipitation reactions, acid-base neutralization reactions, and oxidation-reduction reactions.
• In precipitation reactions a solid product forms from aqueous reactants. The product can be predicted by using solubility rules.
• In acid-base neutralization reactions an acid (proton donor) reacts with a base (proton acceptor) to form an ionic salt and sometimes water. You can recognize this type of reaction by the presence of an acid and base in the reactants.
• In oxidation-reduction reactions (or redox for short) electrons are transferred between reactants. So you will always see changes in oxidation number within this type of reaction.
