What is the role of sodium sulfite in the experimental procedure of the creation of Benzoic acid. -I know that it breaks down any remaining bleach that did not react, but can someone please explain how it works and show an equation to how it works.
Equal volumes of 0.180 M weak base (Kb=2.5x10^-9) and 0.180 M HCl are mixed. Calculate the pH of the resulting solution.
It is burned in excess O2 to form a mixture of water and carbon dioxide that contains 1.5 times as many moles of CO2 as of water. Find the mass of C2H2 in the original mixture.
A mixture of 3.50 moles of B and 5.25 moles of C in a 20.0 L container is allowed to come to equalibrium. What is the equalibrium concentration of A?
A reaction mixture initially contains 0.050 M of all three chemical species in a 0.355 L vessel. What will the concentration of the SO2 be at equilibrium?
if the ethyl alcohol at 35 degree rise through 8.36 cm in a capillary tube of radius 0.20 mm , What is surface tension
The products of a specific reaction and the side products or impurities? Explain specifically what would be observed for this pair of compounds: 4-bromoacetanilide and 2-bromoacetanilide
Indicate whether the potassium acetate salt, CH3CO2K is (A) acidic, (B) basic, (N) neutral
1.664 g of a solid white acid are dissolved in water and completely neutralized by the addition of 45.37 mL of 0.580 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.
Consider the titration of 50.0 mL of 0.217 M HN3 (Ka = 2.6 x 10-5) with 0.183 M NaOH. Calculate the pH of the solution after the addition of 29.6 mL of NaOH solution.
72.0 mL of a 1.40 M solution is diluted to a volume of 278 mL. A 139-mL portion of that solution is diluted using 161 mL of water. What is the final concentration.
What magnitude of current is required to produce 1.0 kg of sodium metal in one hour by electrolysis?
An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 1281 nm and the second at 102.5 nm, to return to the ground state (n=1).
