Answer:

The alkaline solution that turns the ph paper to blue and it produces hydrogen ions.

<u>Explanation:</u>

  • pH is defined as a measure of acid or alkaline level in the water and it indicates the amount of hydrogen molecules in the water.
  • pH value ranges from [0-14], for acidic components pH<7 and base pH>7 and for neutral pH=7.
  • Litmus paper measures the pH values and for acid the color of litmus paper changes from blue to red.
  • For base solutions, the color changes from red to blue.
  • Alkaline solutions change the pH value from red to blue, when it is dissolved in water.

Which of the following is the simplest ketone used as an organic solvent?
Lyrx [107]

Answer: Option (d) is the correct answer.

Explanation:

A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.

For example, acetone CH_{3}-CO-CH_{3} is a ketone.

Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}.

A camphor is a volatile white color substance with chemical formula C_{10}H_{16}O. It has aromatic smell and its taste is bitter.

A menthone is also an organic compound with chemical formula C_{10}H_{18}O.

Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.
