Which of the following reagents is useful in separating benzoic acid from phenol?

Which of the following reagents is useful to separate benzoic acid from phenol ? Solution : 5%NaHCO3 reacts with benzoic acid and not with phenol. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

How do you separate phenol and acid?

For example, a mixture of neutral compound and a carboxylic acid can be separated using bicarbonate ion since only carboxylic acid will be ionized by the bicarbonate ion. Once extracted, the carboxylic acid and phenol can both be recovered by adding HCl to the aqueous solutions.

Is phenol a base or acid?

Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion is, the more likely it is to form.

Why is benzamide neutral?

Benzamide is an extremely weak basic (essentially neutral) compound (based on its pKa). Benzamides are a class of chemical compounds derived from Benzamid, the carbonic acid amide of benzoic acid.

How do you know if it’s a neutral compound?

The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. Polyatomic ions are a set of covalently bonded atoms that have an overall charge, making them an ion. Polyatomic ions form ionic bonds in the typical way, balancing so that the overall compound is electrically neutral.

What is a neutral substance and give 2 examples?

Answer: Neutral substance is a substance that shows no acid or base properties, has an equal number of hydrogen and hydroxyl ions and does not change the colour of litmus-paper. Water, sugar and table salt are common examples of neutral substances.

What are 5 properties of an acid?


  • Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current.
  • Acids have a sour taste.
  • Acids change the color of certain acid-base indicates.
  • Acids react with active metals to yield hydrogen gas.
  • Acids react with bases to produce a salt compound and water.

What is an example of a neutral solution?

An example of a neutral solution is either a sodium chloride solution or a sugar solution. A neutral solution has a pH equal to 7. Water is another common substance that is neutral on the pH scale.

What does a neutral solution look like?

Water and human blood are great examples of neutral solutions. Acids mixed with bases can be neutralized and given a pH of 7. Water can break down to form (H+) and (OH-) ions. When these ions are equal to each other, the value is 1 *10^-7, or neutral.
