Which of these solutes raises the boiling point of water the most? ionic lithium chloride (licl) ionic sodium chloride (nacl) molecular sucrose (c12h22o11) ionic sodium phosphate (na3po4) ionic magnesium bromide (mgbr2)

ionic sodium phosphate

Explanation:

The formula used:

= change in boiling point

i = Van'T Hoff factor  

= boiling point constant

m = molality

1.  For

i= 2 as it is ionic and dissociate to give 2 ions.

2. For

i= 2 as it is ionic and dissociate to give 2 ions.

3. For

, i= 1 as it is a non electrolyte and does not dissociate.

4. For

, i= 4 as it is ionic and dissociate to give 4 ions.

5.  For

, i= 3 as it is ionic and dissociate to give 3 ions.

Thus as vant hoff factor is highest for , the boiling point will be raised most.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
