Strength of Acids and Bases

Strength of Acids and BasesBy Melissa Martin and McKenna Halligan.Strength Of Acids and BasesThe extent to which the acid or base ionises or dissociates in water.

Strong acids and bases are electrolytes that dissociate/ ionize almost completely in water.Weak acids and bases dissociate slightly in water.

Strong AcidsWhen strong acids dissolve in water they ionize.

BufferA Buffer is a solution that is resistant to large changes in pH.ElectrolyteAn Electrolyte is a substance that ionizes or dissociates into ions when it dissolves in water.pHpH is a measure of the hydronium ion concentration of a solution.Weak AcidsWeak acids ionize or dissociate slightly in water.Quiz!Question #1What is a Buffer?Answer #1A Buffer is a solution that is resistant to large changes in pH.Question #2What is an electrolyte?Answer #2An electrolyte is a substance that ionizes or dissociates into ions when it dissolves in water.Question #3What is pH?Answer #3A pH is a measure of the hydronium ion concentration of a solution.Question #4What do strong bases do when they dissolve in water?
