How do you determine if all traces of alkali have been removed?
To determine if all traces of alkali have been removed, you can use pH test strips or a pH meter to check the pH level of the solution. Alkalis typically have a pH above 7, so if the pH level of the solution is neutral (around 7) or slightly acidic (below 7), it indicates that the alkali has been removed. Additionally, performing a bubbling test using acidified phenolphthalein solution can also confirm the absence of alkali if no further bubbles are observed.
How are soluble impurities removed during a recrystallization?
Soluble impurities are removed during recrystallization by dissolving the impure solid in a hot solvent, then filtering the hot solution to remove insoluble impurities. The solution is then cooled slowly, allowing the pure compound to crystallize out while the impurities remain in solution. The pure crystals can be separated from the solution by filtration.
How do particles in solutions can be removed by filtration?
Particles in solutions can be removed by filtration through a process where the solution is passed through a filter that traps the particles while allowing the liquid to pass through. The size of the particles and the pore size of the filter determine which particles are removed. Vacuum filtration or gravity filtration are common methods used to separate particles from solutions.
What are Masking and demasking agents in complexometric titrations?
Masking agents are compounds that selectively bind to interfering ions to prevent them from reacting with the analyte during a complexometric titration, thus masking their interference. Demasking agents are used to release the masked interfering ions so they can react with the titrant or be removed from the solution, allowing for accurate determination of the analyte concentration.
Why did your light bulb stay lit after you removed it from the copper sulfate solution?
The light bulb stayed lit because it retained energy stored from the electrical current passing through the copper sulfate solution. The energy in the bulb continues to provide light until it is depleted.
How insoluble particles can be removed from hot solution?
Insoluble particles can be removed from hot solution by filtration.
What does the state of a solution usually depend on?
The state of a solution typically depends on the solvent used, the solute concentration, temperature, and pressure. These factors determine whether the solution is a solid, liquid, or gas at a given set of conditions.

What is remaining solvent?
Remaining solvent refers to the amount of solvent that still exists in a solution after a process where some of the solvent has been removed or evaporated. It is often measured in terms of percentage or volume to determine the concentration of the solution.

How can the enthalpy change be determined for a reaction in an aqueous solution?
Utilizing a thermometer to measure the temperature change of the solution can be used (along with the mass of the reactant(s)) to determine the enthalpy change for an aqueous reaction, as long as the reaction is carried out in a calorimeter or similar apparatus so that no external heat is added or removed from the system.
What would happen to a loin fish in a hypertonic solution?
The solution will gain water from the fish, till the fish shrinks, and if the fish is not removed from the solution, the fish will die
