Applications of Neutralisation Reactions
Neutralisation Reactions
A reaction between an acid and a base to produce salt and water
Acid + Base 🠒 Salt + Water
Mg(OH)2​+2HCl⟶MgCl2​+2H2​O
Everyday Life Applications
Using baking soda on a bee sting
Bee stings contain formic acid, applying a base to the acid neutralises it decreasing its affects
NaHCO3 (aq) + HCOOH (aq) → HCOONa (aq) + CO2 (g) + H2O (l)
Antacid
Many people suffer from indigestion, which is usually the excess production of hydrochloric acid n the stomach. People use basic antacids to neutralise the excess acid, causing pain relief
Mg(OH)2(s) + 2HCl(aq) → 2H2O(l) + MgCl2(aq)
Common antacid (Magnesium oxide)
Industrial Applications
Farmers use lime (calcium oxide) to neutralise acid soils
Alters soil pH
major factor in optimum soil and crop productivity
Indicator for potential plant growth
Helps reduce heavy metals
Improves microbial activity
Improves structure of soil
improves symbiotic nitrogen fixation by legumes
Improves nutrient availability
A strong base and a weak acid is required to alter soil pH like CaCO3 + H2O ↔ Ca2+ + HCO3- + OH-
Power stations
CaO + SO2 → CaSO3
Acidic gas such as sulphur dioxide, SO2 emitted by power stations and industries is neutralised with lime, CaO before the gas is discharged into the air.
SO2 is a gas, and when reacted with CaO, the resulting calcium sulfite is in a solid state, white in colour. This process reduces the effects of air pollution to an extent.
