Chemistry 1010 Acids and Bases
Molarity The number of moles of solute in 1 liter of solution Moles of Solute Molarity = Liters of Solution
Acid Anything that increases the hydronium ion (H3O+) concentration Anything that donates a proton (H+ ion) H+ + H2O H3O+ HNO3 + H2O H3O+ + NO3- HBr + H2O H3O+ + Br- Acid
Base Anything that increases the hydroxide ion (OH-) concentration Base – substance that can accept a proton Direct – OH- is contained in the baseNaOH + H2O Na+ + OH- + H2OIndirect – OH- is produced in the reactionNH3 + H2O NH4+ + OH-
Strong and Weak One Way or Two Way Arrow O
Properties of Acids • Turn Litmus indicator red • Taste Sour • Dissolve active metals • Produce CO2 when added to limestone • React with bases to form a salt and water
Properties of Bases • Turn Litmus indicatorblue • Taste bitter • Feel Slippery • React with acids to form a salt and water
Common Acids and Bases AcidsBases Vinegar Ammonia Tomatoes Baking Soda Citrus Fruits Soap Carbonated Pop Detergents Gastric Fluid Oven Cleaners Vitamin C Lye Aspirin Drain Cleaners
Acids to know • HCl Hydrochloric Acid • H2SO4 Sulfuric Acid • HNO3 Nitric Acid • HC2H3O2 Acetic Acid
Bases to know • Alkali metal Hydroxides • LiOH Lithium Hydroxide • NaOH Sodium Hydroxide • KOH Potassium Hydroxide • NH3 Ammonia
Neutralization Any time you react an acid with a base you get a salt and water HCl + NaOH NaCl + H2O Acid base salt water HNO3 + LiOH LiNO3 + H2O
Self ionization H2O + H2O H3O+ + OH-
Ways to determine pH • Taste • Litmus Paper • PH strips • Indicators • pH meter • Acids react with metals or carbonates
Titration Experiment • How do you know how much acid is in a solution….......... ………How about Taste It?
