When KCl dissolves in water?

Question

This question I don't get it.

a. the Cl- ions are attracted to dissolved K+ ions.
b. the Cl- ions are attracted to the partially negative oxygen atoms of the water molecule.
c. the K+ ions are attracted to the Cl- ions on the KCl crystal.
d. the K+ ions are attracted to the partially negative oxygen atoms of the water molecule.
e. the K+ ions are attracted to the partially positive hydrogen atoms of the water molecule.

Answer 1

It's d. Water is polar due to the electronegativity difference between oxygen and hydrogen; this makes the oxygen end of the molecule partially negative and the hydrogen end partially positive. The K+ ions are attracted to the negative end of the water molecule, while the Cl- ions are attracted to the positive end.

Answer 2

2KCl+H2O → 2HCl + K2O

KCl is an ionic compound which can only dissolve in ionic compounds like water

when the giant ionic lattice breaks, K+ is attracted to partially negative oxygen (K2O) while Cl- is surrounded by H+ (HCl)

Answer 3

while something dissolves in water, it potential that the ionic bonds ruin aside interior the molecule/formula unit and the water molecules encompass the atoms, allotting the electrical powered can charge. a sturdy anaolgy may well be in case you had the president and the vice chairman at the same time in one circle of guards. in case you dissolve them up, then they flow into separate circles of guards that shield them. because of the fact the water molecules getting between the dissolved ions is what makes the dissolving achievable, then larger temps potential that the molecules flow between the atoms swifter and subsequently ruin them aside extra rapidly.
