A student plans to add HCL to a solution containing pb(NO3)2 (aq). To determine how much Pb2+ will precipitate from solution when the HCL is added, the student needs to know which of the following?A) Ka for HCLB) Ka for HNO3C) Ksp for PbCl2D) Keq for the reaction Pb2+ + 2e- <---> Pb

Option C. Ksp for PbCl₂

Explanation:

The equilibrium constant that is established between a solid and its ions in a saturated solution is what is known as Ksp (solubility product). It is an equilibrium constant based on concentrations.

The concentrations must be equilibrium, that is, concentrations of the ions in a saturated solution. To be sure of such saturation it is convenient to form a precipitate.

The smaller the Kps, the more insoluble the salt

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
