A salt can be acidic, neutral or alkaline. We can deduce the nature of the salt from its constituent ions, namely: 1. ion formed from a weak acid will be a conjugate base, eg CH3COO- (from weak acid CH3COOH) 2. ion formed from a strong acid will be neutral, eg Cl- (from strong acid HCl) 3. ion formed from a weak base will be a conjugate acid, eg NH4+ (from weak base NH3) 4. ion formed from a strong base will be neutral, eg Na+ (from strong base NaOH) This can be summarised as shown: salt hydrolysis nature of ions summary Next we can move on to deduce the nature of a salt. Let's have some...

According to Bronsted-Lowry theory of acids and bases, - an acid is a proton, H3O+ or H+ donor - a base is a proton, H3O+ or H+ acceptor The strength of an acid or base is related to the extent of dissociation in solution: - a strong acid or base is fully dissociated - a weak acid or base is partially dissociated So therefore we will have 4 possible types of acids and bases: 1. Weak Acid 2. Strong Acid 3. Weak Base 4. Strong Base Also, each of these acids and bases will dissociate in solution to give different species. 1. Weak Acid Dissociation eg CH3COOH bronsted theory weak acid CH3COOH...

Balancing Redox Equations via the Half-Equation Method can be done via the following systematic steps. 1. Balance Redox Equation in Acidic Medium Let's have this reaction as an example: balance redox reaction using half equation method example We can determine which species is oxidised and reduced by comparing the oxidation number: - Oxidation state of manganese decreases from +7 to +4 hence MnO4- is reduced - Oxidation state of iodine increases from -1 to 0 hence I- is oxidised We can then write down the half equations for oxidation and reduction: balance redox reaction half equations Next we...
