Frequently Asked Question:
Is lead sulfate soluble in water?
Lead sulfate appears as a white crystalline solid. Insoluble in water and sinks in water. Contact may irritate skin, eyes, and mucous membranes. May be mildly toxic by ingestion, inhalation and skin absorption.

How do you get pbso4?
Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid or by treating a soluble lead salt with sulfuric acid. Alternatively, it can be made by the interaction of solutions of lead nitrate and sodium sulfate.

Is calcium phosphate a precipitate?
Precipitation of calcium phosphate was induced at 21 °C and ionic strength 0.08 by adjusting solutions containing between 2 and 24 moles/l. … Granular precipitate ( Ca P = 1.1.10−1.40. ) apparently formed by rapid conversion of dicalcium phosphate into a more alkaline salt.
What is solubility product of calcium phosphate?
9) The solubility product constant for calcium phosphate, Ca3(PO4)2, is Ksp=1.3 x 10-26.
What is solubility product of calcium phosphate in pure water?
At 25°C and pH 7.00, Ksp for calcium phosphate is 2.07 × 10−33, indicating that the concentrations of Ca2+ and PO43− ions in solution that are in equilibrium with solid calcium phosphate are very low. … As with K, the concentration of a pure solid does not appear explicitly in Ksp.
What is solubility product KSP?
The solubility product constant, Ksp, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. The more soluble a substance is, the higher the Ksp value it has.
What is KSP formula?
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.
How do you find solubility from KSP?
Set up an ICE problem (Initial, Change, Equilibrium) in order to use the Ksp value to calculate the concentration of each of the ions. The concentration of the ions leads to the molar solubility of the compound. Use the molar mass to convert from molar solubility to solubility.
Does calcium phosphate form a precipitate?
Mix DNA with calcium chloride and add in a controlled manner to a buffered saline/phosphate solution. Incubate at room temperature to generate a precipitate of extremely small, insoluble particles containing condensed DNA. Add the DNA-calcium phosphate co-precipitate to cells, which adhere to the cell membrane.
Is calcium phosphate soluble?
Calcium phosphate is insoluble in water but soluble in acids: it is used in natural farming. Calcium phosphate may dissolve slightly in CO2-containing water.
