What is the purpose of an indicator? to cause a change in ph to identify the ph of a solution to identify bases only in a solution to identify acids only in a solution

to identify the pH of a solution

Explanation:

Indicators are substances whose colour solutions change due to changes in the pH. They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra. they are usually used during titration to indicate end points of an experiment. The colour of an indicator alters when the concentration of a certain chemical species, reaches a critical range of values.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

the answer is sex-linked recessive.
