The sulphate ion is SO4-2
Charge is -2
Use:
Number of Eq = number of mol * charge
= 0.500 * 2
= 1.00 Eq
= 1.00*1000 mEq
= 1000 mEq
Answer:
1.00 Eq
1000 mEq

What is the molar concentration of sulfate ions in a 0.500 M CS2SO4 solution? O 0.500 M 1.50 M 1.00 M 0.250 M
The precipitate did not dissolve because sulfate ion is too weak a base. The amount of sulfate ion that reacts with the hydronium ion is too small to cause a shift in the equilibrium sufficient to dissolve a signiticant amount of the insoluble sulfate. In general, the anion of a precipitate must be a stronger base than fluoride ion in order for the precipitate to be dissolved by the addition of a strong acid. After the reactions with barium ion,...

Label three test tubes as either "Carbonate Ion Test", "Sulfate Ion Test", or "Phosphate Ion Test". Add two mL of the unknown solution into each test tube. Using the unknown solution, follow the procedures for the Test for Carbonate Ion, Test for Sulfate Ion, and the Test for Phosphate determination in the corresponding test tubes. The unknown solution is used as a substitute for the known samples which were used in Experiment 1. Record your results of each test in...
Suppose that a 2.00L glass flask is 0.500 mol of H2 and 0.500 mol Cl2 are reacted to produce HCl. When equilibrium is reached, the concentrations of HCl is found to be 0.110M. What is the keq? (ICE box, Keq expression & Keq value)
