What is the KSP equation of Ca OH 2?

What is the KSP equation of Ca OH 2?

The apparent equilibrium constant, Ksp, can be calculated from the molar solubility of calcium hydroxide: Ksp = [Ca2+][OH-]2.

How is Ca OH 2 named?

calcium compounds Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide.

What is the other name for quick lime?

Quicklime is the common name for burnt limestone, calcium oxide (CaO).

What is the accepted value of the KSP for calcium hydroxide?

The accepted value of the Ksp for calcium hydroxide is 5.02 x 10 .

Is Ca OH 2 an acid or base?

Common examples of strong Arrhenius bases are the hydroxides of alkali metals and alkaline earth metals such as NaOH and Ca(OH)2.

How do you find the concentration of Ca OH 2?

Concentration of Ca(OH)2 in the Saturated Solutions Calculate the concentration of Ca(OH)2 in the saturated solution by dividing the number of moles of Ca(OH)2 by the volume of saturated solution used in liters.

What is Ca OH 2 used for?

Ca(OH)2 can be used in the paper industry during the Kraft process, which converts wood into wood pulp. In the sewage treatment process, calcium hydroxide can be used as a flocculant or clarifying agent. It is an important compound in ammonia preparation.

Is CaO acidic or basic?

Calcium oxide (CaO) , is a metal oxide. Like other metal oxides it is a basic oxide because it dissolves in water to form calcium hydroxide.

Is slaked lime acidic or basic?

Its solubility decreases with increase in temperature. Its suspension in water is called milk of lime. It is insoluble in alcohol. It is basic or alkaline is nature.

What is the pH of a saturated solution of Ca OH 2?

about 12.4
In fact, the pH of a saturated calcium hydroxide solution is about 12.4.

Is Ca Oh 2an acid or base?

Ca(OH)2 is a strong base. A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. Each mole of sodium hydroxide dissolves to give a mole of hydroxide ions in solution.

What are some common uses of Ca(OH) 2?

Uses of Calcium Hydroxide In the process of sewage treatment, calcium hydroxide is used as a clarifying agent or as a flocculant. Ca (OH) 2 is used in the paper industry during the Kraft process of converting wood into wood pulp. It is a very important compound in the preparation of ammonia. This compound is also used as a pH modifier due to its basicity.

What does Ca(OH)2 stand for?

Ca(OH)2 is Calcium Hydroxide. It is generally referred to as Slaked lime. It is a white powder and is colourless in the crystalline form. It is generally prepared when Calcium oxide(quick like) is slaked over water.

What is the molarity of the Ca(OH) 2 solution?

Molarity of Ca (OH)2. A sample of solid Ca (OH)2 is stirred in water at 30 C until the solution contains as much dissolved Ca (OH)2 as it can hold. A 100 mL sample of this solution is withdrawn and titrated with 5.00 x 10^-2 M (Molarity) HBr . It requires 48.8 mL of the acid solution for neutralization.

What is the name base Ca(OH)2?

Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca ( OH) 2. It is a colorless crystal or white powder. It has many names including hydrated lime, caustic lime, builders’ lime, slaked lime, cal, or pickling lime.
