The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.

<h3 /><h3>What is indicator?</h3>

In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security.

Answer:

The half life is $H_{1/2}= 7333.3sec$

Explanation:

The half life of a first order reaction is mathematically represented as

$H_{1/2} = \frac{0.693}{Rate Constant }$

Substituting $9.45 * 10^{-5}s^{-1}$ for the rate constant

$H_{1/2} = \frac{0.693}{9.45*10^{-5}}$

$H_{1/2}= 7333.3sec$

Alja [10]

Answer: The bonds are intermediate between double and single bonds

Explanation:

A closer look at the diagram below shows that the bonds in sulphur IV oxide are intermediate between double and single bonds. Hence they do not have the exact bond angle of single bonds. This is why the bond angle is not exactly 120°. There are two resonance structures in the diagram that clearly show this point.
