I need the answer as soon as possible

Give detailed Solution with explanation needed..don't give Handwritten answer

How long would it take to titrate 1.00 mmol H2S with a current of 100.0 mA?

A 0.0712-g sample of a purified organic acid was dissolved in an alcohol-water mixture and titrated with coulometrically generated hydroxide ions. With a current of 0.0392 A, 241 s was required to reach aphenolphthalein end point. Calculate the equivalent mass of the acid.

Write the chemical equation

5. A 17.1769 mL sample of an acid was titrated with electrogenerated OH-. It took 617s at a constant current of 0.216A to reach a phenolphthalein end point. Determine the molarity of the acid.

What happens when too much NaSCN is prepared in solution of mixtures of standard solutions of Fe(NO3)3 and NaSCN, so that [SCN^-] is higher than expected? What does this do to the measured Keq?

What are the respective concentrations (M) of Fe3+ and I- afforded by dissolving 0.200 mol FeI3 in water and diluting to 725 mL? A) 0.276 and 0.828 B) 0.828 and 0.276 C) 0.276 and 0.276 D) 0.145 and 0.435
