Properties of Acids They taste sour (Never taste acids in the science lab!). They turn litmus & universal indicator red Acids react with metals- they eat it away Corrosive Acids react with metals (they form H2 gas ) All acids form hydronium ions (H+) when mixed in water.

They turn litmus paper & universal indicator blue. Properties of Bases They taste bitter (Never taste bases in the science lab!). They turn litmus paper & universal indicator blue. They feel slippery. All bases form hydroxide ions (OH-) in water.
