Acids generally have a sour taste and a pH less than seven.These molecules react with bases to form salts. Two types of acids exist: inorganic acids (such as hydrochloric acid and sulphuric acid) and organic acids (such as formic acid and acetic acid). By neutralisation, the acidic and basic property of both the acid and the base are destroyed. Lime and baking soda are two affordable and readily available chemicals that neutralise acids.
Put on safety goggles, an acid-resistant apron and rubber gloves. Keep a source of fresh water nearby to use in case of any accidental splashes or spills.
Dissolve 4 to 5 cups of baking soda in a 5-gallon bucket filled with approximately 1/4 water. Pour the acid slowly into the bucket until the fizzing stops, and dispose the solution. For spills, neutralise the acid by pouring raw baking soda or lime over the spills until the fizzing stops.
Absorb the neutralised acid with dry sand or dirt, and collect it in an appropriate chemical waste container for disposal.
