Question

the ideal Indicator for titration of strong acid and weak base range ph
(a)5-8
(b)4-6
(c) 8-0​

Answer 1

titration of strong acid and weak base- (b)4-6

Explanation:

• Methyl Orange is an indicator that's accustomed indicate the equivalence point of the acid−base titration. within the acidic environment, it turns red and within the basic environment, or pH of 4.
• In a weak base-strong acid titration, the acid and base will react to make an acidic solution. A conjugate acid are going to be produced during the titration, which then reacts with water to make hydronium ions. This leads to an answer with a pH under 7.
• A strong acid will react with a weak base to create an acidic (pH < 7) solution. a robust acid will react with a powerful base to make a neutral (pH = 7) solution. A weak acid will react with a powerful base to make a basic (pH > 7) solution.

Answer 2

Answer:

The ideal Indicator for the titration of a strong acid and a weak base is in the ph range of 4-6.

Explanation:

Acid-Base Titration is a process that is used for various purposes like knowing the concentration of acid or base and knowing the respective strength of the acid and base.

For the process, we use a titrant(solution for which the strength is known)  and a strand(the solution for which the strength is to be known).

After the titration, to detect the endpoint, an indicator is used. The role of the indicator is that it would show a colour change and hence indicate a certain ph. They do so by knowing the equivalence point.

The Equivalence point is the time point at any titration when the concentration of the added titrant can neutralize the given strand.

For the titration of a strong acid and a weak base, for example, Hydrochloric acid and  Ammonia, the ideal indicator used is primarily Methyl orange which is a weak acid with the ph in the range of 4-6.
