1. When cobalt chloride is added to pure water, the Co2+ ions hydrate. The hydrated form then reacts with the Cl–ions to set up the equilibrium shown here:
|
Co(H2O)62+ + 4Cl– CoCl42– + 6H2O |
|||
|
(pink) |
(blue) |
||

Calcium hydroxide and lead chloride both have limited solubility in neutral water. When acid is added, the solubility of calcium hydroxide goes way up. but that of lead chloride doesn't change. Which statement explains the acid impact? Ca(OH)_2(s) Ca^2+ (aq) + 2 HO^(aq) K = 4.7 x 10 - 6 PbCl_2(s) Pb^2+ (aq) + 2 Cl-(aq) K= 1.6 times 10-5 HO-(aq) + H+(aq) - H2O(1) a Acid reacts with the calcium ions that are produced. b.

10. When sodium chloride
dissolves in water, the ions dissociate: NaCl (s) = Na+
(aq) + Cl- (aq)
Write ionic equations, similar to the one above, that describe
how NaNO3 and NaCH3CO2 each
dissociate as they dissolve in water. Include heat as a reactant or
product in each equation.
Here is what I answered:
NaNO3 (s) = Na+ +
NO3- + heat
NaC2H3O2 + Heat =
Na+ +
C2H3O2-(ag)

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
