what are acids,bases and salts?? definition plz!!
Acids are substances having a sour taste. The word ‘acid’ comes from a Latin word ‘acere’, which means sour. Acids are corrosive and react with bases to form salt and water. Also, acid turn blue litmus paper red. For example hydrochloric acid (HCl), sulphuric acid (H2SO4) are acids.
Bases are defined as chemical substances which are bitter to taste and soapy to touch. They react with acids to form salts and turn red litmus paper blue. For example sodium hydroxide (NaOH), potassium hydroxide (KOH), magnesium hydroxide [Mg(OH)2] etc.
Salt is defined as the product formed along with water when an acid reacts with a base. The reaction between an acid and a base forming salt is known as neutralisation reaction. The general equation for the neutralisation reaction is represented as:
Acid + Base → Salt + Water
For example, when sodium hydroxide (NaOH) is treated with hydrochloric acid (HCl), then a salt, sodium chloride (NaCl) and water (H2O) are obtained. The chemical equation for the is given as:
NaOH + HCl → NaCl + H2O
