Acid — definition?
Substance increasing H⁺ in solution.
pH — definition?
Logarithmic measure of 0H^+ concentration.
pH scale — range?
0 to 14, measures acidity or alkalinity.
[H^+] — effect on pH?
Higher 0H^+ lowers pH.
Strong vs weak acids — difference?

pH 7 — solution type?
Neutral solution.
pH less than 7 — solution?
Acidic solution.
pH greater than 7 — solution?
Alkaline (basic) solution.
Strong acids — dissociation?
Complete dissociation in water.
Weak acids — dissociation?
Partial dissociation in water.
