What is Strong Acid?

A strong acid is an acid that is totally ionized in a solution. A strong acid will react with a

strong base to form a neutral (pH = 7) solution. completely ionized

strong electrolyte ionic/very polar bonds

3. HI2 HI H2 + I2

4. HBr H2O + HBR H3O + BR

5. HNO3HNO3 + H2O H3O+ + NO-

What Is Strong Base?

A strong base is a base that is completely dissociated in an aqueous solution.

Strong bases LiOH - lithium hydroxideNaOH - sodium hydroxideKOH - potassium hydroxideRbOH - rubidium hydroxideCsOH - cesium hydroxideCa(OH)2 - calcium hydroxideSr(OH)2 - strontium hydroxide

Ex: NaOH(aq) Na + OH-

Continue…1. LiOH

LiOH → Li+ OH-

2. NaOHNaOH → Na + OH-

3. Ca(OH)2 Ca(OH)2 Ca2+ + 2OH-

4. Sr(OH)2

Sr(OH)2 Sr2+ + 2OH-

pH ScaleThe pH scale measures how acidic or basic a solution is. pH stands for Power of Hydrogen

pH = - log [H3O+ / H+]
