Biology 1201 pH and pOH Calculations Disclaimer: these questions are more difficult than the questions on the exam. Do not use a calculator for 1-11 1) Determine the pH of a 0.001 M HNO 3 solution. 2) Determine the pOH of a 0.0001 M HNO 3 solution. 3) What is the pH and pOH of [H + ] = 1.0 x 10 - 5 M 4) What is the pH and pOH of [OH - ] = 1.0 x 10 - 3 M 5) The pH of a solution is 3.0. What is the [OH - ]? 6) If the base has an OH - concentration of 0.001M, find the pH. 7) One liter of a solution pH 9 has how many more hydroxyl ions (OH - ) than 1 L of a solution of pH 4? 8) An acidic solution (lemon juice) has a pH of 3. If I dilute 10mL of this solution with

Unformatted text preview: water (pH 7) to a final volume of 1000mL, what is the pH of the resulting solution? 9) An acidic solution ha s a pH of 6. If I increase the OH-concentration by 1000 what is the pH of the resulting solution? What’s the pOH? 10) A solution with a pH of 3 has ____________ H+ ions then a solution of pH 7. 11) A solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral. Why? Hard one (use a calculator) 12) What is the pH of a solution that contains 25 grams of hydrochloric acid (HCl) dissolved in 1.5 liters of water?...
