It is not possible to determine whether silver chloride is more or less soluble than ___ by simply comparing Kspvalues.

Answer 1

Without doing any calculations it is possible to determine that silver chloride is more soluble than ACD, and silver chloride is less soluble than ___.

It is not possible to determine whether silver chloride is more or less soluble than B by simply comparing Ksp values.

Step-by-step explanation:

The Lead (Pb) is a heavy metal and Zinc (Zn) is a transition metal, both combine with the anion phosphate produces heavy complexes very insoluble.

The silver cation (Ag+) is an acid cation which in basic conditions rapidly precipitates as AgOH which is highly insoluble and unstable.

The FeCO3 is a complex with a solubility relatively close between AgCl. The Kps of these two are
`3.2x10^(-11)` and
`1.8x10^(-10)` respectively at room temperature.
