Of the things you can likely find on the kitchen/garage shelf. Sodium
bicarbonate, carbonate, ammonia and sodium hydroxide (careful) as bases
in rough order and acetic acid, citric acid (lemon juice), sulphuric,
hydrochloric acid as a strong acids.

Take care with any strong alkali or acid they can be unforgiving.



But how would I know what pH reading I should get from them ?
i.e is lemon juice pH 1,2,3,4 ?
