How will you estimate Zn2+ in zinc sulfate solution by titrimetric method? Explain in detail with chemical structure of required indicator.

How the Ca2+ can be analyzed if its reduced form does not have any selective indicator

A 11.3 sample of CaCO₃ was treated with aqueous H₂SO₄, producing calcium sulfate, water and 3.65 g of CO₂(g). What was the % yield of CO₂?

A metal M exists in two forms M^b+ and M^a+ (b > a). When a current of 2 A is passed through a 1 L aqueous solution of 0.01 M M^b+ for 965 s, 0.005 mol of the metal was deposited at the cathode while the concentration of M^a+ in solution was found to be 0.005 M. Assuming that the reduction process takes place stepwise and equal moles of electrons are consumed in both the reduction reactions, find the value of a × b.

The density of air at 20°C and 1 atm is 1.205g/L. If this air were compressed at the same temperature to equal the pressure at 40.0m below sea level, what would b it's density? Assume the barometric pressure is constant at 1 atm . The density of sea water is 1.025g/cm³

The student has two solutions separated by a semipermeable membrane that only allows water to pass through it. The right side of the membrane has 3.0 moles of compound A (MW = 350 g/mol), and the left side has 2.0 moles of compound B (MW 150 g/mol). What do you think will happen to the solution? Rise on the right, rise on the left, or remain at a matching level on both sides?
