Acid and Base Eureeka Review Get paper, pencil Get reference table Get calculator Which of the following is the best conductor of electricity? NaCl (s) NaCl (aq) C6H12O6 (s) C6H12O6 (aq) ANSWER NaCl (aq) Which solution is the best conductor of electricity? 0.1 M HNO3 0.1 M CH3COOH 0.1 M C6H12O6 0.1 M C2H5OH What happens to the conductivity of a solution if KCl is added to a saturated solution of KCl? In a 0.01 M solution of HCl, blue litmus will do what? In the below reaction, which quantity would be considered the proton donor? HF + H2O H3O+ + F- Pure water is similar to 1.0 M HCl in that they both Contain H3O+ Are neutral to litmus Have a pH higher than 7 Are good conductors of electricity According to the Bronsted-Lowry theory, an acid is any species that can . . . When tested, a solution turns red litmus to blue. This indicates that the solution contains two types of ion. Which ion is more abundant? What will water become if it acts as a base? H3O+ In the reaction below is water an acid, a base, or both? H2 O + H 2 O H3 O + + OH - BOTH Which salt will hydrolyze in water to create a basic solution? NaNO2 What does this mean? CaCl2 BaI2 React each with water . . MgSO4 If the product is a strong base and a weak acid, it will be a basic solution. NaNO2 + H2O NaOH + HNO2 Note the mole ratio is 2:2 How many mL of 1.0 M H2SO4 are needed to exactly neutralize 15 mL of 2.0 M Ba(OH)2? 30mL As 50mL of 0.1 M HCl is added to 100mL of 0.1M NaOH, the pH of the NaOH will do what? Write a chemical equation that would represent a neutralization reaction. NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l) A water solution contains 0.50 moles of HCl. How many moles KOH should be needed to neutralize the acid? 0.50 moles How many grams does that represent? 28.5g What is the pH of a solution if the HYDROXIDE ion concentration is 1 x 10-4 moles per liter? 10 What is the [H3 O+] of a 0.001 M HCl solution? 1.0 x 10 -3 M You find an unknown solution in the lab What characteristics will it have if it is a base? What characteristics will it have if it is an acid? BASE: ACID: pH=↑7 pH=↓7 Slippery Sour Litmus: blue Litmus: red Pheno: pink Pheno: colorless Proton acceptor Proton donor Caustic [OH-] ↓ [H+] [OH-] ↑ [H+] What materials will you need if you are going to do titration to see what the concentration of the chemical is? Burets, beakers, acid and base (one with an unknown concentration), phenolphthalein, Erlenmeyer flask THE END!! HOW DID YOU DO?
