Answer 1

A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.

Answer 2

The correct statement is:

A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.

Answer 3

The correct statement is: A solution of potassium hydroxide will always have a higher pH than a solution of ammonia.

To understand why this is the correct statement, we need to understand the properties of bases and how they affect pH.

The pH scale is a measure of the concentration of hydrogen ions (H+) in a solution. The pH scale ranges from 0 to 14, where 0 is highly acidic, 7 is neutral, and 14 is highly basic.

A base is a substance that can accept a proton (H+) or donate hydroxide ions (OH-) in a chemical reaction. The concentration of hydroxide ions (OH-) in a solution affects its pH. The higher the concentration of hydroxide ions, the higher the pH.

Ammonia (NH3) is a weak base. When dissolved in water, it accepts a proton (H+) from water molecules, forming the ammonium ion (NH4+) and hydroxide ions (OH-). However, the extent to which ammonia accepts protons is relatively low, resulting in a lower concentration of hydroxide ions in the solution. Therefore, ammonia has a lower pH compared to stronger bases.

Potassium hydroxide (KOH) is a strong base. It completely dissociates in water, releasing potassium ions (K+) and hydroxide ions (OH-). Since it fully ionizes, it produces a higher concentration of hydroxide ions in the solution. As a result, potassium hydroxide has a higher pH compared to ammonia.

So, the statement "A solution of potassium hydroxide will always have a higher pH than a solution of ammonia" is correct. The other statements regarding concentration, ions, and conductivity are not necessarily true, as they depend on the specific concentrations and conditions of the solutions.
