Alum salt

Alum is both a specific chemical compound and a class of chemical compounds. The specific compound is the hydrated potassium aluminium sulfate(potassium alum) with the formulaKAl(SO4)·12H2O. More widely, alums are double sulfate salts, with the general formula AM(SO4)2·12H2, where A is amonovalent cation such as potassium orammonium and M is a trivalent metal ion such as … Continue reading Alum salt


A salt is an ionic compound that results from the neutralization reaction of an acid and a base.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic, such as chloride (Cl−), or … Continue reading Salt

Ionic Compound

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic … Continue reading Ionic Compound
