When a diprotic acid is titrated with a strong base, and the Ka1 and Ka2 are significantly different, then the pH vs. volume plot of the titration will have

A solution containing CaCl2 is mixed with a solution of Li2C2O4 to form a solution that is 2.1 × 10-5 M in calcium ion and 4.75 × 10-5 M in oxalate ion. What will happen once these solutions are mixed? Ksp (CaC2O4) = 2.3 × 10-9.

The following pictures represent solutions of CuS, which may also contain ions other than Cu2+ and S2- which are not shown. Gray spheres represent Cu2+ ions and dotted spheres represent S2- ions.If solution (1) is a saturated solution of CuS, which of solutions (2)-(4) are unsaturated?

Which of the following compounds will have the highest molar solubility in pure water?

In which of the following solutions would solid PbCl2 be expected to be the least soluble at 25°C?

The following pictures represent solutions at various points in the titration of a weak acid HA with aqueous KOH. Unshaded spheres represent H atoms, black spheres represent oxygen atoms, and shaded spheres represent A- ions. (K+, H3O+ initially present, OH- initially present and solvent water molecules have been omitted for clarity). Which picture represents the solution after the equivalence point?

A change in pH will significantly affect the solubility of which, if any, of the following compounds?.

Which one of the following changes of state increases the entropy of the system?

What is the difference between a fibrotic liver and a cirrhotic liver?

Cirrhosis of the liver is associated with development of ascites and varices. Which of the following correctly identifies the portion of the circulatory system that would most affect the development of ascites and varices and the most significant pressure change within that circulatory compartment that would cause ascites and varices?
