What compound is most soluble in water?
Among given compounds, ethylene glycol ( HO−CH2−CH2−OH ) is the most soluble in water. Ethylene glycol has two hydroxy groups both of which form hydrogen bonds with water. Greater is the number of hydrogen bonds, greater is the extent of hydrogen bonding and greater is the solubility in water.
| Soluble in Water | Important Exceptions (Insoluble) |
|---|---|
| All Group IA and NH4+ salts | none |
| All nitrates, chlorates, perchlorates and acetates | none |
| All sulfates | CaSO4, BaSO4, SrSO4, PbSO4 |
| All chlorides, bromides, and iodides | AgX, Hg2X2, PbX2 (X= Cl, Br, or I) |
The small polar compound methanol, CH3OH, is the most soluble in water.
1 Answer. Hexan – 1 – ol compound is least soluble in water .
Among given compounds, ethylene glycol ( HO−CH2−CH2−OH ) is the most soluble in water.
Sodium chloride, also known as common salt or table salt, is a chemical compound with the formula NaCl. Its mineral form is called halite. It is highly soluble in water and is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms.
Sodium chloride
Hydrogen (H2) is not soluble in water this is because hydrogen is a non-polar molecule whereas water is a polar molecule.
So, out of the four given compounds ,we can predict that $MgS$ has the maximum amount of covalent character, which makes it the least soluble compound. Hence, the answer is option (B).
In Alkanes, hydrogen bonds can not be made at all (with themselves OR water) because alkanes are non-polar and do not contain a functional group that allows them to hydrogen bond. Alkanes are not soluble in water.
What 2 types of compounds will dissolve in water?
Water is a polar molecule therefore, it will dissolve polar solutes such as, ionic compounds and polar molecular compounds.
Sodium chloride
1 Answer. Polar solutes or ionic solids dissolve best in water.
When polar compounds or ions are added to water, they break up into smaller components, or dissolve, to become part of the solution. The water's partial charges attract different parts of the compound, making them soluble in water.
2. All sodium, potassium, and ammonium salts are soluble in water.
Carbon dioxide is only water-soluble, when pressure is maintained. After pressure drops the CO2 gas will try to escape to air. This event is characterised by the CO2 bubbles forming into water.
Calcium chloride
