using an universal indicator, or you can use litmus paper or a pH meter.
Litmus paper
Hydrion paper is specific for bases!
A litmus paper is a indicator that is used to test for acids or bases
Yes, concentrated acids and bases are more corrosive than dilute acids and bases
Of course they are. They are many acids and bases
bases neutralise the acids
They don't dissolve (or more properly, dissociate) completely in water, only partially. Acids or bases that dissociate completely are called strong acids or bases.
acids and bases are important!
Of course they are. They are many acids and bases
Acids taste bitter.
They either have a high concentration of H+ ions (acids) or OH- ions (bases). Strong acids and bases are also highly corrosive relative to weaker more neutral acids/bases.
Acids have a lower PH and bases have a higher PH.
