The indicator methyl red has different molecular structures at high and low pH. a. True
b. False

a. True

Explanation:

Methyl red is an indicator widely used in quality control of oxides as Zinc oxide in the titration with sulfuric acid.

As is used in titrations of acid-base reactions the indicator change in colour. Is red when the pH < 4.4 (Acidic Solutions) and is yellow when pH > 6.2 (Neutral-Basic solutions).

A change in colour means the structure of the indicator is changing with pH. Thus, the answer is:

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
