IB Chemistry 3.1.9 (HL) pOH scale Questions
Practise calculating pOH and pH from hydroxide ion concentration for strong alkalis and bases that release more than one OH− per formula unit.
How this is tested
- calculate pOH from [OH−] and then determine pH for strong alkali solutions
- deduce [OH−] by accounting for stoichiometry in bases such as Ca(OH)2
- identify pH values of strong bases such as KOH from their stated concentration
