Question

Chemistry

A water sample is prepared by adding 10-4M NaCl, 10-3 M NaHCO3and 10-4 M CaCl2 to water. Assume that when these salts dissolve,they dissociate to Na+, Cl- , Ca2+, and HCO3 - and then do notreact further. a. Compute the ionic strength of the solution. b.What is the activity of each dissolved ion if the infinitelysolution approximation applies and the infinite dilution scale isused? What is the activity of each ion if the extended Debye-Huckelequation applies? c. Calculate the activities of all ions if theNaCl concentration is increased by three order of magnitude to 0.1M to model an estuarine water.
