What is KSP equation?

What is KSP equation?

In general, MaXb(s) <=> aM+b(aq) + bX-a(aq) is expressed as Ksp = [M+b]a[X−a]b. These expressions are called solubility product constant expressions because they involve the product of the equilibrium concentrations of the constituent ions, each raised to the power corresponding to the number of ions in the formula.

Is Pb3 PO4 2 a solid?

Lead phosphate has the formula Pb3(PO4)2, and the accepted practice for writing the solubility reaction of a sparingly soluble compound that will dissociate into a cation and anion is shown. The solid is always shown on the left, or reactant side.

What is the KSP of Pb3 PO4 2?

Ksp for Pb3(PO4)2 is 1.0×10^-54.

What 4 factors affect solubility?

Factors affecting solubility

  • Temperature. Basically, solubility increases with temperature.
  • Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
  • Pressure. Solid and liquid solutes.
  • Molecular size.
  • Stirring increases the speed of dissolving.

What is the solubility of Al OH 3 in the presence of 0.2 M NaOH?

The molar solubility of Al(OH)_(3) in 0.2 M NaOH solution is x xx 10^(-22)”mol/L”. Given that, solubility product of Al(OH)_(3)=2.4xx10^(-24).

Does higher KSP mean higher molar solubility?

The higher the Ksp, the more soluble the compound is. Ksq is defined in terms of activity rather than concentration because it is a measure of a concentration that depends on certain conditions such as temperature, pressure, and composition. Ksp is used to describe the saturated solution of ionic compounds.

Is phosphate a solid?

Phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.

Is Lead II phosphate a solid liquid or gas?

Lead(II) phosphate appears as hexagonal, colorless crystals or as a white powder. Lead(II) phosphate is insoluble in water and alcohol but soluble in Nitric acid (HNO3) and has fixed alkali hydroxides.
