Base and Acids

Acids: Taste sour Sticky pH less than 7 release H+ ion in solution Conduct Electricity in water Molecular Compound Acids neutralize bases producing a salt and water Acids react with active metals to produce hydrogen  Acids react with carbonates to produce a salt, water and CO Binary Acids:Acids made of two elements, hydrogen and non-metalE.g. HClNomenclature: Hydrochloric AcidOxyacids:Acids made of hydrogen and polyatomic ionE.g. H2SO4Nomenclature: Chloric Acid

Bases: Taste bitter Slippery pH more than 7 Release OH- ion in solution Conduct Electricity in water Ionic Compound, electrolyte Bases neutralize Acids producing a salt and water Bases can contain hydroxide, carbonate or bicarbonate E.g. LiOH Nomenclature: Lithium Hydroxide

The pH scale measures how acidic or basic a substance is.  It ranges from 0 to 14 A pH less than 7 is acidic  a pH greater than 7 is basic Pure water is neutral, with a pH of 7.0 X10 

Common Indicators: Thymol Blue acid: yellow, base: blue Bromothymol blue: Yellow base: blue
