6. Acids in Solution
An acid is any substance that forms hydrogen ions (H+) in water. These H ions cause the properties of acids you can see.
Acids have one or more positive Hydrogen ion and a negative ion of something else. For example: HCl water H⁺+Cl⁻

7. Bases in Solution
A base is any substance that forms hydroxide ions (OH⁻) in water.
Hydroxide ion is made of oxygen and hydrogen and has a negative charge.
When bases dissolve in water the positive ions and hydroxide ions separate. Example: water
NaOH Na⁺+ OH⁻
If there is no hydroxide in a base, when it is in solution, it reacts with the water to form hydroxide ions.

8. What makes a strong acid? What makes a strong base?
Strong acid: Most of the molecules break up into ions in solution. Fewer break up in a weak acid.
Strong base: More OH ions are produced in solution then for weak bases.
