pH stands for “power of hydrogen”

The pH scale is a measure of the H⁺ ion concentration of a substance in water.

Explain qualitatively the pH range of 0 to 14

• Universal indicator 
• Phenolphthalein

• Strong acids and alkalis ionize (almost) completely, therefore they have a large concentration of free ions in solution which makes them highly conductive. 
• Weak acids and alkalis ionize only partially, therefore have a low concentration of free ions in solution which gives them poor conductivity.

Neutralization = The reaction of an acid with a base to produce a salt and water. 

• Acids release H⁺  into solution.
• Bases release OH^- into solution. 
• If we were to mix an acid and base together, the H⁺ ion would combine with the OH^- ion to produce the molecule H₂O.

DEF OF TITRATION = A technique for determining the concentration of an acidic or basic solution. The solution with known concentration is added to the solution of unknown concentration in a very controlled way to neutralise it by forming a salt and water. 

A salt = A substance in which the hydrogen of an acid has been replaced by a cation, e.g. NaCl
