Ammonia is a weak base. Potassium hydroxide is a strong base. Which statement is correct?
A solution of potassium hydroxide will always have greater connectivity than a solution of ammonia.
A solution of potassium hydroxide will always have more OH- ions in a solution of ammonia.
A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.
A solution of potassium hydroxide will always have a lesser concentration of solute than a solution of ammonia.
Please answer soon!
A makes no sense to me. I don't know what "connectivity" means.
B makes absolutely no sense to me.c, d are not true.
I don't believe C and D are always true.
It was supposed to say conductivity sorry
Also B states - A solution of potassium hydroxide will always have more OH- ions THAN in a solution of ammonia.
A is certainly true if the concentrations are the same.
B would be true if the concentrations are the same but the word "in" throws me for a loop.
I don't be believe C and D are true all the time
To find the correct statement, let's analyze the properties of ammonia and potassium hydroxide as bases.
Ammonia (NH3) is a weak base because it partially dissociates in water to produce hydroxide ions (OH-) and ammonium ions (NH4+). In a solution of ammonia, not all ammonia molecules will react with water, leading to a limited number of OH- ions.
Potassium hydroxide (KOH), on the other hand, is a strong base because it completely dissociates in water to produce hydroxide ions (OH-) and potassium ions (K+). This complete dissociation ensures a high concentration of OH- ions in the solution.
Now let's examine each statement:
1. "A solution of potassium hydroxide will always have greater connectivity than a solution of ammonia."
Connectivity is not a term typically used to compare bases, so this statement is irrelevant and not correct.
2. "A solution of potassium hydroxide will always have more OH- ions in a solution of ammonia."
This statement is correct. Since potassium hydroxide fully dissociates in water, it will have a higher concentration of OH- ions compared to ammonia.
3. "A solution of potassium hydroxide will always have a higher pH than a solution of ammonia."
This statement is also correct. The pH scale is a measure of the concentration of hydrogen ions (H+) in a solution. Since potassium hydroxide has a higher concentration of OH- ions than ammonia, it will result in a lower concentration of H+ ions, leading to a higher pH.
4. "A solution of potassium hydroxide will always have a lesser concentration of solute than a solution of ammonia."
This statement is incorrect. The concentration of solute in a solution depends on the amount of base dissolved and the volume of the solution. It cannot be generalized that the concentration of solute in potassium hydroxide is always lesser than in ammonia.
