The pH scale
pH scale This scale is used to determine the concentrat’n of H + ions versus OH - ions Things that are neutral are pH 7, acids are below 7 and bases are above 7
pH scale As you go from pH 7 to pH 8 there are 10 times more OH - ions Every level of the pH scale represents a ten fold (ten times) increase in the concentration of the H + or OH - ions
pH Scale So how much more acidic is lemon juice with pH 2 than saliva pH 6? 10 000! How much more basic is bleach pH 13 than sea water pH 8

Acids, Bases, and Solutions
PH and pOH Chem 332 – ODette. pH (Potential of Hydrogen) Measures the degree of acidity or basicity of an aqueous solution Corresponds to the hydrogen.
PH and Concentration. pH Recall water H 2 O H + + OH - Every water molecule produces one hydrogen ion and one hydroxide ion At equilibrium, K eq = [products]
PH Relative concentration of H + ions in water HOH ↔ H + + OH - O HH
Aqueous solutions & concepts of pH Chapter I. Ion Product constant - water A. Acids→ hydronium ions (H 3 O+) Bases → hydroxide ions (OH-) B.Self.
Ch. 8. pH Scale Used to measure how acidic or basic a substance is Ranges from 0-14.
Environmental Science Lesson 6 - pH. Everyday pH pH is both in and around us all the time Body organs require certain pH to function Food/drink.
PH The wonders of water!. Acids Any compound that GIVES OFF H+ ions in solution Any compound that GIVES OFF H+ ions in solution Ex. HCl H+ and Cl- Ex.

Acidity, Basicity, and pH
Chemistry Chapter Acids and Bases. (Self-Ionization of Water) H 2 O + H 2 O H 3 O + + OH - Two water molecules collide to form Hydronium and.
The pH scale.
Ways to measure Acidity/Basicity What is pH? What is pOH?
Ch.15: Acid-Base and pH Part 1.
Acids and Bases. Ionization of Water H 2 O + H 2 O H 3 O + + OH - K w = [H 3 O + ][OH - ] = 1.0
PH Scale. Ion product constant for water K w H 2 O H + + OH - K w = [H + ] [OH - ] = 1.0 X mol/L Since [H + ] = [OH - ] for water Then each equals.
PH of Common Substances Timberlake, Chemistry 7 th Edition, page 335.
Continuing into the world of acids and bases…. pH of a solution is the negative logarithm of the hydrogen ion concentration pH = -log [H + ] This.
