Answer : The correct option is, (A) The hydronium ion concentration in the solution.

Explanation :

Acid-base indicator : It is used in the titration. It is a substance which changes the color with the pH.

Acid-base indicator are the weak acid-base indicators which when dissolved in the water, it dissociate slightly and form the ions.

When the indicator dissolved in the water then it dissociate into H^+ ion and then the color change of the pH indicator.

Let us consider an indicator which is a weak acid, with the formula HIn.

At equilibrium, the chemical equation of acid indicator will be,

HIn \rightleftharpoons H^++In^-

Hence, the correct option is, (A) The hydronium ion concentration in the solution.

There are two formulae that could be used to determine the mechanical advantage of an inclined plane which stated as MA = Length/rise and Wout=Win. MA is the mechanical advantage, Wout is the output force, Win is the input force, and "rise" is the height of the inclined plane<span>.</span>

MArishka [77]

Answer:

It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the equator because the poles are closer to the center of the earth due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but increases toward the center.
