Q. Why are ionic compounds not soluble in water?
Water breaks the ionic bond by hydrogen bonding, as, water itself has a more ionic bond and polar in nature. Many other solvents such as kerosene and petrol are not capable of breaking the ionic bond. Hence, can not dissolve them, and they all have covalent bonds and which are non-polar in nature.
Q. Which compound is more 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.

Q. How do you know which compound is most soluble?
2 Answers. It depends on the solution and the solute. Usually, the rule is “like” dissolves “like”. A polar solution will dissolve polar compounds and a non-polar solution will dissolve non-polar compounds.
Q. Which compound is the least soluble in water?
octane
Q. Why should crushing rock salt make it dissolve faster?
The crushed salt dissolve faster than table salt, since when the salt in crushed into small crystal, its surface area is increased therefore it dissolve faster as compared to table salt which has large surface area.
Q. How does crushing affect solubility?
Crushing it has really no affect on solubility because we have not heated it at all. Crushing it has increased the surface area so it speeds up the dissolving process but doesn’t change maximum solubility. Crushing it has really no affect on solubility because we have not stirred it at all.
Q. Does increasing pressure increase solubility?
The solubility is a measure of the concentration of the dissolved gas particles in the liquid and is a function of the gas pressure. As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up, as you decrease the pressure, the solubility goes down..
Q. Why does increasing pressure increase solubility?
In general, the solubility of a gas in a liquid is increased by the increase of pressure. As the molecules collide more with the liquid’s surface, they will be able the squeeze between the liquid molecules and thus become a part of the solution.
Q. Why does higher temperature increase solubility?
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
Q. Will increasing temperature always increase solubility?
Increasing the temperature will therefore increase the solubility of the solute. An example of a solute whose solubility increases with greater temperature is ammonium nitrate, which can be used in first-aid cold packs.
Q. At what pressure does air dissolve into water?
Percentage saturation can be indicated in terms of the constituent gases, or in terms of the total dissolved gases: At an atmospheric pressure of 760 mm Hg (NTP) the partial pressure of oxygen (pO2) will be 159 mm Hg i.e. At 100% air saturation solubility of oxygen at 30°C is 7.54 mg/l (see Table 1).
Q. Which three events will make a solute dissolve faster in a solvent?
How can we make the solute dissolve faster?
- We can make the solute dissolve faster by heating the mixture. Heating the sugar and water mixture.
- We can make the solute dissolve faster by stirring the mixture.
- We can make the solute dissolve faster by grinding the solute before it is put into the solvent.
Q. What are 3 ways to get something to dissolve faster?
The rate of dissolving of a solute in a solvent is faster when the solute and solvent are stirred, the solvent is warmer, or the solute consists of smaller particles with more surface area.
Q. Can dissolve the solute faster?
Dissolution is a surface phenomenon, since it depends on solvent molecules colliding with the outer surface of the solute. A given quantity of solute dissolves faster when it is ground into small particles, rather than in the form of large pieces, because more surface area is exposed.
Q. What are 3 ways to speed up dissolving?
If you are trying to dissolve a substance, you have three primary avenues to increase the dissolution rate: decreasing the particle size of the solid, increasing the temperature and/or increasing the mixing or stirring rate.
Q. Which solute dissolves faster in hot water?
Sugar
