Assuming that no equilibria other than dissolution are involved, calculate the concentration of all solute species in each of the following solutions of salts in contact with a solution containing a common ion. Show that changes in the initial concentrations of the common ions can be neglected.

(a) TlCl(s) in 1.250 M HCl

(b) PbI2(s) in 0.0355 M CaI2

(c) Ag2CrO4(s) in 0.225 L of a solution containing 0.856 g of K2CrO4

(d) Cd(OH)2(s) in a solution buffered at a pH of 10.995

Solutions

Expert Solution

Four given salts are sparingly soluble salts. Its solubilty is already less and it is more supressed by the common ion effect. Concentration of common ion increased by the dissociation of salt is very very less and we can neglect that concentration .

There are ~350,000 species of angiosperms, and there are less than 40,000 species of all other land plants combined. What evolutionary process resulted in this rapid accumulation of biodiversity from an original, ancestral lineage? In the case of the angiosperms, what specific evolutionary innovations related to angiosperm reproductive biology were likely involved with this explosion in biodiversity? In what way did these novel features allow angiosperms to become so diverse. Present evidence (to the extent we covered it in the...
