Excess ca(oh)₂ is shaken with water to produce a saturated solution. the solution is filtered, and a 50.00 ml sample titrated with hcl requires 11.21 ml of 0.0983 m hcl to reach the end point.
calculate for ca(oh)₂. compare your result with that in appendix d. do you think the solution was kept at 25°c?

The solubility product of calcium hydroxide is .

Explanation:

To calculate the concentration of acid, we use the equation given y neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is .

We are given:

Putting values in above equation, we get:

Molarity of calcium hydroxide solution = 0.01102 M

1 mole of calcium hydroxide gives 1 mole of  calcium ions and 2 moles of hydroxide ions.

Solubility product is given by:

The solubility product of calcium hydroxide is .

6.4 cm (max) - 25 cm (min)

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
