(a)
Interpretation:
It should be determined whether the carbonate transposition will be effective for detecting SO42- from BaSO4 or not.
Concept introduction:
Carbonate transposition is a reaction which leads to determine that the slightly soluble solids’ aqueous medium anion concentration is sufficient for qualitative analysis.
(b)
Interpretation:
It should be determined whether carbonate transposition will be effective for detecting Cl- from AgCl or not.
Concept introduction:
Carbonate transposition is a reaction which leads to determine that the slightly soluble solids’ aqueous medium anion concentration is sufficient for qualitative analysis.
(c)
Interpretation:
It should be determined whether the carbonate transposition will be effective for detecting F- from MgF2 or not.
Concept introduction:
Carbonate transposition is a reaction which leads to determine that the slightly soluble solids’ aqueous medium anion concentration is sufficient for qualitative analysis.

The pH of normal, unpolluted rainwater is controlled by carbonic acid equilibrium: COz(g) > COz(aq) + H2CO3° (a) Write down the equilibrium expressions (K) for the three carbonate reactions. Mat 16 (b) What is the pH of rainwater in equilibrium with atmospheric CO2 (Pco2 = 10-3.5 atm)? Assume that the pH will be controlled by dissociation of carbonic acid (H₂CO3º) to HCO3- (i.e., [HCO3] [H*]). Hence need consider only the first and the second reactions in the series of carbonate reactions. Known Kco2 = 10-1.46, K₁ = 10-6.35, pH = -log[H*]. (INATE) 14arrow_forward
