Hydrogen Ions and Acidity

Hydrogen Ions and Acidity. The Ionization of Water and pH. Hydrogen Ions in Water. We are used to thinking of water as a pure liquid that contains only H 2 O molecules. However, as a pure liquid, water ionizes into hydrogen ions and hydroxide ions: H 2 O( l ) ? H + ( aq ) + OH - ( aq )

Bases

Bases. Who's on first?. Back to Our Color-Coded Scale. What about the right-hand side of this?. Some Questions. 1. If pH comes from [H + ], how do you have a pH in base, which doesn't have any H+? 2. What makes something a base in the first place?. Once Again, in Reverse.

Ionization of Water

pH. Ionization of Water. When compounds dissociate/ionize in and aqueous solution, they produce ions - hydronium ( H 3 O + ) and hydroxide ( OH - ) T hese ion concentrations can be expressed more easily as [H 3 O + ] = 1.0 x 10 - 7 M and [OH - ] = 1.0 x 10 - 7 M.

pOH

pOH. What is the [H + ]?. If the [H + ] = 1 x 10 -7 M, the pH = 7. That works well with acids, but what about bases? Consider sodium hydroxide: NaOH(aq) ? Na + + OH - What is the [H + ]?. We need a new formula!!. Since bases release hyroxides, OH - , we will calculate the pOH.
