A solution is made by combining 15.0 mL of 18.0M acetic acid with 5.50g of sodium acetate and diluting to a total volume of 1.50 L.
Calculate the pH of the solution.
What is the chemical balance equation and what causes the color and precipitation?
What is the volume (in mL) needed to make a 0.1273 M NaOH solution with 0.02534 moles of NaOH?
Determine the calorimeter constant of the calorimeter in which the combustion of 0.600 g of sucrose raises the temp by 1.96 C
Barium fluoride has a Ksp of 1.0X10^-6. What is the barium ion concentration in a saturated solution where the fluoride concentration is 0.035M? Please show the steps needed to reach the end.
describe an experiment that you could perform in lab that would provide the data so you could calculate the Ka value for sulfamic acid, HSO3NH2.
Predict stereochemistry of the products formed if the addition of bromine to fumaric acid occurs via Syn addition
A 30.00 mL solution of potassium nitrate (KNO3) was diluted to 125.0 mL, and 25.00 mL of this solution were then diluted to 150.0 mL. The concentration of the final solution is 0.00307 M. Calculate the concentration of the original solution.
A student assay a solution of H3PO4 by titrating 20.00mL of the solution with .01020M NaOH. An endpoint at ph 5 was observed after 10.11 mL of NaOH had been added.
The liquid is allowed to stand in contact with the solid until equilibrium is achieved and then the liquid is poured off. What is the mass of solid remaining?
A 25.0-mL sample of 0.150 M butanoic acid is titrated with a 0.150 M NaOH solution. What is the pH before any base is added? The Ka of butanoic acid is 1.5 x 10-5.
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
