What is pH? pH is a measure of how acidic or basic a solution ispH of a solution is compared to the pH scale
pH Scale: Ranges from 0 to 14,a pH of less than 7 is acidic, a pH greater than 7 is basic, a pH of 7 is neutral
pH Scale pH 0 = Battery AcidpH 1 = Hydrochloric Acid produced by the stomach pH 2 = Lemon Juice, Vinegar pH 3 = Grapefruit, Orange Juice, Soda pH 4 = Tomato Juice, Acid Rain pH 5 = Black Coffee pH 6 = Urine, Saliva pH 7 = “Pure” Water
pH 8 = Sea Water pH 9 = Baking Soda pH 10 = Milk of Magnesia pH 11 = Ammonia pH 12 = Soapy Water pH 13 = Oven Cleaner pH 14 = Liquid Drain Cleaner
Testing pH To test pH we can use two testsLitmus paper pH paper Litmus Paper: turns red if the solution is acidic and turns blue if the solution is basic pH Paper: changes to a specific colour for the pH of that solution

Quick Review Acids produce H + (also written as H ) ions in water Bases produce OH - ions in water H + + OH - → H 2 O An acid plus a base yields.
PH SW classify substances according to their pH by conducting a lab activity. SW explain the relationship between values on the pH scale by using scientific.
September 22, 2014 The pH scale measures how acidic or basic a substance is. The scale ranges from 0 (most acidic) to 14.0 (most basic). A pH of 7.0 is.

Acids and Bases. How acidic a substance is, or how basic a substance is, is measured on a scale known as the pH scale. This is a logarithmic scale that.
