The sulfate ion level in a municipal water supply is given as 46.0ppm .

What is [SO2?4] in this water? in units M

Expert Solution

Given the level of sulfate ion is 46.0 ppm

= 46.0 mg / L

Molar mass of sulfate ion , SO₄^2- is = At.mass of S + (4xAt.mass of O )

= 32 + (4x16)

= 96 g/mol

So the concentration of sulfate ion is = [SO₄^2- ] = 46.0 mg / L

= 46.0x10^-3 g / L Since 1g = 10³ mg

= 46.0x10^-3 gx(1/96)(mol/g) /L

= 4.79x10^-4 mol/L

= 4.79x10^-4 M

In acidic solution, the sulfate ion can be used to react with a number of metal ions. One such reaction is SO42−(aq)+Sn2+(aq)→H2SO3(aq)+Sn4+(aq) Since this reaction takes place in acidic solution, H2O(l) and H+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation: SO42−(aq)+Sn2+(aq)+ −−−→H2SO3(aq)+Sn4+(aq)+ −−− What are the coefficients of the reactants and products in the balanced equation above? Remember to include H2O(l) and H+(aq) in the appropriate blanks....

When an organic sulfate ester is hydrolyzed by a sulfatase enzyme, a hydrogen ion is produced; R-O-SO3- + H2O ----> ROH + SO4-2 + H+ The above reaction was carried out in a 1.0 mL of a .02 M Tris buffer, pH 8.10, containing 0.01 M ester. At the end of 10 minutes, the pH of the reaction mizture decreases to 7.95. How many micromoles of ester were hydrolyzed during the 10 minute reaction period? pKa of Tris = 8.10.
