The calcium chloride produced in the solvay process can be used in the production of road salt.however it is sometimes discharged as waste into the sea by coastal industrial plants .describe a simple test and its results that can be carried out on a sample of seawater to monitor if calcium chloride has been discharged into the sea.
10 tonnes of limestone is added to 15 tonnes of brine. By using the overall reaction of the process.determine which of the raw materials are in excess.calculate the maximum mass of sodium carbonate that can be produced with these raw materials. Hence calculate the actual mass of sodium carbonate produced if the percentage yield of the process is 84.5%

A reaction produced 0.50 mmol of H+ in a buffered solution which contained 500 ml of 0.08 M succinate buffer, pH 4. What was the pH of the medium after the reaction was completed? The pka of succinic acid is 4.21
Why is it that there is no temperature during melting and boiling when we know that there is?
The equilibrium constant for the autoprotolysis of water, H2O (l) H+(aq) + OH−(aq), is Kw =
[H+][OH−] = 1.008 × 10−14 at 298 K. After a temperature-jump, the reaction returns to
equilibrium with a relaxation time of 3.7 x 10-5 s at 298 K and pH ≈ 7. Given that the forward
reaction is first-order and the reverse is second order overall, calculate the rate constants for the forward and reverse reactions.
