What is the maximum concentration of lime milk?

What is the maximum concentration of lime milk?

Answer:

Take 2ml lime milk solution and hold it to 250ml capacity bottle. Mix. Take 50ml into 150ml conical flask, to join 1mol/L 2ml NaOH solution concentration, pH transferred to 12-13, adding a little murexide indicator powder, solution is pink, with two 0.0100mol/L sodium EDTA solution to pale purple as the end point of titration.
Lime milk, chemical formula Ca (OH) 2, commonly known as slaked lime, lime water, or lime, the maximum concentration is about 80% - 90%, white solid, slightly soluble in water, its water solution is often called the lime water, can reduce the concentration of the solution for seed decomposition.
