Astudent who is performing this experiment pours an 8.50 ml sample of the saturated borax solution into a 10 ml graduated cylinder after the borax solution had cooled to a certain temperature t. the student rinses the sample into a small beaker using distilled water, and then titrates the solution with a 0.500 m hcl solution. 12.00 ml of the hcl solution is needed to reach the endpoint of the titration.
calculate the value of ksp for borax at temperature t.

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x. xx ml
