What is the accepted KSP value for calcium hydroxide?
What is the accepted KSP value for calcium hydroxide?
6.5 × 10–6
8 The approximate value of the Ksp for calcium hydroxide is 6.5 × 10–6, so calculate a rough value of the concentration of OH– ion, [OH–], in the saturated solution (see prelab question on WebAssign; to two significant figures).
Which is the correct KSP expression for Ca OH 2?
The apparent equilibrium constant, Ksp, can be calculated from the molar solubility of calcium hydroxide: Ksp = [Ca2+][OH-]2.
What would be the KSP for the dissolution of Ca OH 2?
You use the solubility product constant to calculate the solubility of a sparingly soluble electrolyte like calcium hydroxide. The solubility product constant for Ca(OH)₂ is 5.5 × 10⁻⁶.
Does higher KSP mean higher solubility?
The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.
Is calcium hydroxide a strong base?
Some strong bases like calcium hydroxide aren’t very soluble in water. That doesn’t matter – what does dissolve is still 100% ionised into calcium ions and hydroxide ions. Calcium hydroxide still counts as a strong base because of that 100% ionisation.
Is Ca OH 2 aqueous or solid?
Calcium hydroxide, commonly referred to as slaked lime, is described by the chemical formula Ca(OH)2. It is an inorganic compound which has a white, powdery appearance in its solid-state.
How do you calculate KSP?
Calculating the K sp from the Molar Solubility. 1) Write the chemical equation for the substance dissolving and dissociating. 2) Write the K sp expression . 3) Insert the concentration of each ion and multiply out. Example #1: Determine the K sp of silver bromide, given that its molar solubility is
What are the products of calcium hydroxide?
Calcium hydroxide is an odorless white powder. It’s used in industrial settings, such as sewage treatment, paper production, construction, and food processing. It also has medical and dental uses. For example, root canal fillings often contain calcium hydroxide.
Is calcium hydroxide soluble in water?
In the case of calcium hydroxide, it is slightly soluble in water (about 1.7 g/L at 20 degrees Celsius) Calcium hydroxide is produced, however, when calcium oxide is mixed (or slaked) with water.
What is the molar solubility of calcium hydroxide?
The molar solubility of calcium hydroxide can be calculated using the solubility constant. Therefore, the molar solubility of calcium hydroxide at pH 5 is 1×10^-9 mol/. To calculate for the molar solubility of Ca (OH)2 for other pH values, do the same steps to arrive at the answer.
