3.Cold water is added to each of the following pairs of solid salts. In each case state whether a precipitate wil be present, and if so what its composition is. Note: The precipitate may be either one or both of the original salts or one or more of the products formed by reaction between the salts. (10 pts) a. Pb(C2H2O2)2 and NaCl b. BaSO4 and Cus c. Ni(NO3)2 and CaCl2 d. AgCl and Cu(NO3)2 e. Na2CO3 and MgCl2 4. In...

"Hard" water contains mainly salts of Ca2+ and Mg2+, both of which form many insoluble salts. You have a water sample and need to determine whether it contains Ca2+ and/or Mg2+. When you add ammonia to the solution, followed by ammonium chloride and ammonium oxalate, a white precipitate of CaC2O4 should form if Ca2+ is present. What is the purpose of adding the ammonium chloride to the reactant mixture? a. The chloride ion helps to form the calcium chloride precipitate....

It is important to think through the reactions that are occurring (or not occurring) and determine how you can rule out the presence of a certain metal ion or how you can posi- tively identify its presence. Use the Solubility Table 1 and Appendix 1 of this manual to understand the precipitation réactions that are observed. You need to consider both the anion and the cation that react to form a given precipitate. The color and the general ap- pearance...

2. What differences did you notice when you added acid or base to distilled water as compared to the buffer solutions? The blood buffer system is made up of H2CO, and HCO3-. Describe with the use of equations how this system responds to added H3O* and to added OH". 4. Looking at the fractional speciation curve, what is important about the point of intersection between the intermediate species and both the acidic species and basic species? Compare the same point...
