When Acids are added to Water, what do they Form?
Positively Charged Hydrogen Ions, H+.
What makes a Solution Acidic?
The Presence of H+ Ions.
When Alkalis are added to Water, what do they Form?

What is pH?
The Ionising Power of Hydrogen Ions in a Solution.
When does a Neutralisation Reaction Occur?
When an Acid & Alkali React, & Water is Produced.
What is Produced in a Neutralisation Reaction?
Water. H2O.
Very Acidic Solutions have very Low…
pH.
Very Alkaline Solutions have very High…
pH.
When a Metal Reacts with an Acid, it is not a Neutralisation Reaction. Why?
Because Water isn’t Produced, only Salt & Hydrogen.
