General Chemistry
Calculate [Ca2+] when 50.0 mL of 0.40 M CaCl2 and 80.0 mL of 0.15 M CaCl2 solutions are mixed. Assume volumes are additive.
The dissolution reaction shown below:
KMnO4 (s) → K+ (aq) + MnO4- (aq)
What are the concentrations of the two ions if the KMnO4 solution is 1.20 M.
Assuming that volumes are additive, find the concentration of each ion in the solution obtained when 3.80 g of MgBr2 is dissolved in 200.0 mL of 0.0150 M NaBr solution.
What is the molarity of NO3– in each solution?
(i). 0.250 M NaNO3
(ii). 0.250 M Ba(NO3)2
(iii). 0.250 M Al(NO3)3
