What else can I help you with?
What are the two criteria that must be met for a substance or a solution to exhibit electrolyte behavior?
For a substance or solution to exhibit electrolyte behavior, it must be composed of ions that can move freely in the solution and the substance must be able to conduct electricity when dissolved in a solvent.
Is carbonated water a pure substance?
For a substance to be pure, it must have no impurities in the substance. Carbonated water is water with carbon dioxide and other substances dissolved in this. Hence, it is not a pure substance.
Is tetrachloromethane an electrolyte?
Carbontetrachloride, CCl4, is not an electrolyte. To be an electrolyte, the solution must contain dissolved ions. All pure liquids, with only a few exceptions, are not electrolytes.
How do solids dissolve in liquids?
By being heated up and turning into either a gas or a liquid.
Is H2o2 an electrolyte?
Yes, hydrogen peroxide (H2O2) is considered a weak electrolyte because it partially dissociates into ions in solution, producing hydrogen ions (H+) and peroxide ions (O2^2-). However, it does not fully ionize like strong electrolytes such as acids, bases, and salts.
What two requirements are necessary for a substance to be an eletrolyte?
For a substance to be an electrolyte, it must be able to ionize or dissociate into ions in solution. Also, it must conduct electricity in solution due to the presence of these free ions.
What type of compound is most likely to be a strong electrolyte?
Ionic compounds are most likely to be strong electrolytes because they dissociate completely into ions when dissolved in water, allowing for the flow of electricity. This is in contrast to molecular compounds like sugar, which do not dissociate into ions and are therefore weak electrolytes or nonelectrolytes.
What is the composition of solution?
Solution: a solute (or more) in a solvent. Solute: the dissolved substance in a solvent. The solute must be soluble in the solvent.
Is it true that the temperature must drop lower than 0 Celsius for water to freeze when a solute is dissolved in the water?
Yes if something is dissolved in the water then it is no longer pure water and the freezing point will change
Is sea water an mixture?
It must be. Minerals and salts are dissolved in the liquid, but do not react with the water. No reaction, no compound.
What must happen to water in order for its dissolved minerals to be deposited?
Water must evaporate or cool down in order for its dissolved minerals to be deposited. As the water evaporates or cools, it becomes supersaturated with minerals, causing them to come out of solution and form solid deposits. This process is known as precipitation.
Does the temperature must drop 0 C for water to freeze when a solute is dissolved in the water?
A solute added to water decreases the freezing point.
