Strong Bases

According to Arrhenius, bases are substances that increase the WHAT of a solution

According to Arrhenius, bases are substances that increase the HYDROXIDE [ ] of a solution

All WHAT are strong bases

All IONIC HYDROXIDES are strong bases

eg) NaOH, Ca(OH)2, Al(OH)3

% reaction = WHAT

100%

Strength depends on the WHAT… Ba(OH)2 is a WHAT base than NaOH at the same concentration because it produces WHAT

Strength depends on the NUMBER OF HYDROXIDE IONS… Ba(OH)2 is a STRONGER base than NaOH at the same concentration because it produces 2OH-

Whats the equation for strong bases

[OH- (aq)] = x[SA (aq)]

[OH- (aq)] = x[SA (aq)] where x is the number of WHAT ions (think about the dissociation equation)

[OH- (aq)] = x[SA (aq)] where x is the number of HYDROXIDE ions (think about the dissociation equation)

Once you have the [OH], you can calculate the WHAT using WHAT or WHAT

Once you have the [OH], you can calculate the pH using pOH or Kw
