RAM Ready And Motivated Mon 1111 Prove that

RAM - Ready And Motivated Mon 11/11 Prove that the following chemical equation is NOT balanced. H 2 + O 2 H 2 O Rewrite the equation so that it will be balanced. Unit 2 Test – 11/20

Standard and LO 7. P. 2 The student will demonstrate an understanding of the structure and properties of matter and that matter is conserved as it undergoes changes. 7. P. 2 B. 3 Analyze and interpret data to compare the physical properties and chemical properties (neutralization to form a salt, reaction with metals). Unit 2 Test – 11/20

Notes • p. H is the measure of how acidic or basic a solution is. • Solutions are classified as acids, bases, or neutrals depending on p. H level. • Indicators are used to measure p. H of a solution. • The p. H measurement range of a solution is between 0 -14. Unit 2 Test – 11/20

Notes • Many household cleaners are classified as bases. • The formula of a base can be recognized because the formula typically ends in OH. • The formula of an acid can be recognized because the first element in the formula is typically hydrogen. • If a base is combined with an acid a chemical reaction will occur and the products will be water and salt. • Example : HCl + Mg (OH)2 = Mg. Cl + H 2 O • (ie. Stomach acid + Antacid Salt + Water) Unit 2 Test – 11/20

Notes Acids • p. H < 7 • Neutralization occurs when acids react with bases • Reacts with metals to give off a gas • Forms a salt and usually water • Reacts with blue litmus paper turning it red • Does not react with red litmus paper leaving it red • Does not react with phenolphthalein • Sour taste • Sticky texture • Examples: stomach acid, vinegar, orange juice Unit 2 Test – 11/20

Notes Bases • p. H > 7 • Neutralization occurs when bases react with acids • Forms a salt and usually water • Reacts with red litmus paper turning it blue • Does not react with blue litmus paper leaving it blue • Reacts with phenolphthalein turning it magenta • Bitter taste • Slippery texture • Examples: baking soda, drain cleaner, Tums Unit 2 Test – 11/20

Notes Neutrals • p. H = 7 • Neutralization occurs when bases react with acids • Neither acid nor base • Reacts with red or blue litmus paper turning it violet • Does not react with phenolphthalein • Example: purified water Unit 2 Test – 11/20

Notes Litmus paper • Has a special dye on it that changes colors in the presence of an acid or base. • Blue litmus paper turns red in an acid and stays blue in a base. • Red litmus paper turns blue in a base and stays red in an acid. Unit 2 Test – 11/20

Notes Phenolphthalein • Is used to test for the presence of a base. • It is a colorless chemical that turns magenta (bright pink) in a base • It stays colorless in neutral or acidic solutions. Unit 2 Test – 11/20

RAM - Ready And Motivated Thurs 11/14 Begin by writing “RAM” and the date at the top of your next page. Then write the following questions leaving space for your answers. Bog Bodies 1. Hypothesize why bog acids react differently with the bones of the bodies than they do with the organs, hair, and skin. The calcium in the bones react with the acid in the Bogs breaking them down. The organs, hair and skin do not react with the acid. 2. How are pickles similar to bog bodies? They are both preserved in the acid Unit 2 Test – 11/20 Pearson – Chapter 4 –Lesson 3
