For a titration experiment: I am using 1.025 M of NaOH(aq) as my titrant. My titration solution is 4.0 g of potassium hydrogen tartrate, with 300 mL of distilled water. After 4 trials, my average NaOH used was 1.680 mL. I am having problems figuring out how to calculate my findings. Each trial started with 50 mL of potassium hydrogen tartrate solution, and 2 drops of phenophthalein. Then I added 1.680 mL of NaOH (on average) to get titration to...

22) In a laboratory experiment, some sodium fluoride was dissolved in distilled water at 25°C. The pH of the final solution was measured to be 8.6 at 25°C. After heating the solution on a hot plate, the pH was measured to be 8.9. Explain why the pH increased after the solution was heated. F + H2O FH + OH AH = +118.4 kJ/mol

Suppose compound X has a solubility of 20.0g per 100mL in ether and 12.1g per 100mL is water. In all cases, explain your reasoning and show your work clearly (i.e. show the equation(s) you are using, the values you plug in, and the final answers, BUT you don't need to show all the algebraic steps.) a. Determine the partition coefficient k. b. What mass of compound X will you retrieve when an aqueous solution containing 30.0g of X in 300.mL...
