In this video we determine the type of chemical reaction for the equation H3PO4 + Ca(OH)2 = Ca3(PO4)2 + H2O (Phosphoric acid + Calcium hydroxide).
Since we have an acid and a base in the reactants and an ionic compound (a salt) and water in the products, this is a Neutralization Reaction. Neutralization reactions follow the general form of:
HX + MOH → MX + H2O
Where X is a non-metal and M is a metal.
For example: HCl + NaOH = NaCl + H2O
---Type of Reactions---
Synthesis (Combination): A + B → AB
Decomposition: AB → A + B
Single Replacement : A + BC → B + AC
Double Replacement: AB + CD → AD + BC
Combustion: CxHy + O2 → CO2 + H2O
Neutralization: HX + MOH → MX + H2O
Reduction-Oxidation (Redox): Electrons are exchanged. Many of the above reactions are redox
Note that neturalization reactions are often double displacement reactions as well.
Being able to determine the type of reaction by looking at reactants can help in predicting the outcome of the chemical reaction.
