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

Acid / Base Worksheet Answer the questions to the Acid/Base worksheet by clicking through the following slides that were made by you and your classmates.
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.
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.

Pg of composition notebook. Acid: Substance that donates Hydrogen ions (H + ) to a solution. Or forms H 3 O + (hydronium ions) with water
Acids & Bases By Robert McGee. Our Goals for today To determine the difference between Acids & Bases Discuss the importance of studying Acids & Bases.

describe the properties of acids and bases? be able to read a ph scale, and understand what it represents describe neutralization.
Measured on a pH scale (0-14). Is a compound that dissolves in water to form a solution with a pH lower than 7 Examples: Vinegar Lemon Juice Acid Rain.
Chapter 20 pH. Water forms ions H 2 O ----> H + + OH - Water splits apart into hydrogen ions (H+) and hydroxide ions (OH-). This process is called self-ionization.
Acids, Bases & pH. What are Acids? Acids taste SOUR –Lemons, vinegar Compounds that have Hydrogen (H + ) as their cation. Examples: –HCl – Hydrochloric.
What happened?!?!?!?. Billy was a chemist’s son, but now he is no more. What he thought was H 2 O was H 2 SO 4.
Indicators For Acids & Alkalis
