A solution is prepared by combining .025 mole CaCl2 and .015 mol Pb (NO3)2 and adding water to make 1L of solution. Will a precipitate of PbCl2 form in this solution?
If 100mL of 0.01 M CaCl2, 100mL of 0.01 M Sr(NO3)2 and 100 mL of 0.01 M Na2SO4 are mixed together; what is the Ca2+ concentrationin solution and which precipitates will form?
The double-replacement reaction between silver-nitrate and sodium bromide produces silver bromide, a component of photographic film.
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.560 moles of a monoprotic weak acid
The reaction of benzanilide with Cl2in acetic acid yields a mixture of 2 monochloro derivatives formed by electrophilic aromatic substitution.
