Answer to Question #140699 in General Chemistry for firas

Question

3) Solution 3 (molarity of a diluted solution): Prepare 10 mL of a 0.040M potassium hydroxide solution by dispensing a calculated volume of solution 2 into a 10-mL volumetric flask, using a volumetric pipette, and then diluting to the mark. Once you have prepared your solution, measure the pH with a pH meter.

4) Solution 4 (molarity of a diluted solution): Prepare 50.0 mL of a 0.050M hydrochloric acid solution using the 0.10M solution available to you and a volumetric pipette. Once you have prepared your solution, measure the pH using a pH meter.

5) Solution 5 (reaction of solution 3 and 4): Measure out equal 10 mL volumes of solution 3 and solution 4 using volumetric pipette into a 50-mL beaker. Once you have prepared your solution, measure its pH.
