Sucrose is insoluble in dichloromethane because dichloromethane is not a polar solvent.
Sucrose is soluble in water because the molecules of sucrose has the ability to react with the molecules of water and thereby forming hydrogen bond which enhance the dispersion of sucrose in the water.
Sugar can not react in a similar way with dichloromethane because they do not possess chemical species that can react together to form bonds. Thus, sugar is a polar substance which can not dissolve in a non-polar solvent.
This would be a proton.It has a positive charge and is found in the nucleus. Don't get it confused with an electron this is not inside the nucleus but floats around the nucleus.
The formula that connects Ka1, Ka2, and Ka3 is the relation;
Ka = Ka1 * Ka2 * Ka3
<h3>What is the Ka?</h3>
The Ka is defined as the acid dissociation constant of a solution. Now we have the triprotic acid called phosphoric acid. this implies that we have Ka1, Ka2, and Ka3.
Thus the formula that connects Ka1, Ka2, and Ka3 is the relation;
Ka = Ka1 * Ka2 * Ka3
