Which yields H+(aq) as the only positive ion in an aqueous solution?(1) CH3CHO (2) CH3CH2OH (3) CH3COOH (4) CH3OCH3
Answers
CH3CHO is an aldehyde called acetaldehyde.
CH3CH2OH is an alcohol called ethanol
CH3OCH3 is an ether called dimethyl ether.
and finally, the answer CH3COOH is a weak acid called acetic acid.
Answer:The correct answer is option (3).
Explanation:
Carboxylic acid gives ions in their aqueous solution.
Carbonate ion formed is stabilized due to resonance.
Whereas aldehyde in their aqueous solution do not give ions.
Alcohol in their aqueous solution do not give ions.
Ether in their aqueous solution do not give ions.

An ion is a charged molecule or atom. It is positively when there are more protons than electrons. You call it positive ion.
It is negatively charged when there are more electrons than protons. It is called anion.

- Chip stones should be added to a solution that is to be refluxed as they act as nucleation sites for formation of solvent bubbles.
- This should be added when the temperature of the liquid is still low.
What are Boiling Chips?
These are usually added to a solution as they contain trappedair which
helps in the reflux process.
The high surface area ensures it acts as nucleation sites and the best time
to dd is when the temperature of the solution is still low for best results.

The solute must be able to react with water at the given temperature.
There must be enough energy to break the chemical bonds in the water molecules.
The temperature must be high enough to cause the solute to melt.
Answers
In order for a solute to dissolve in a solvent, the attractive forces between solute particles and the solvent particles must be stronger than the attractive forces between solute-solute and solvent-solvent particles. This is important so that the solute will remain in solution.
