Acidic buffer is solution which containing high concentration of weak acid and its conjugate base. Its pH would remain relatively constant when adding small amount of acid or base.i.e. CH₃COOH...

Ionic bonding: When a metal loses electron(s) and a non-metal gains electron(s) to achieve a full outer shell For example, sodium chloride (NaCl) Points to make: Which atom lose...

Al has the higher first ionisation energy. Mg electronic configuration is [Ne]3s² whereas Al configuration is [Ne]3s²3p¹. To remove the electron from Al, it has to be remo...

Crude oil is a mixture of hydrocarbons with varying length carbon chains. The main method used to separate these is fractional distillation. The crude oil is heated, then placed inside a fractionating col...

Ionisation energy is the energy required to remove one electron from an isolated gaseous atom (in its ground state). This generates a cation (ion with a positive charge).
Both Mg and Al are in period...
