Answer:

...BY CHOOSING A PROPER INDICATOR, SCIENTISTS CAN MINIMIZE THE DIFFERENCE IN THESE TWO NUMBERS,...

Explanation:

A chemical indicator is an agent or substance which gives a visible sign especially a color change when introduced to a solution of base indicating the threshold of the concentration of acid used in the titration procedure. These indicators include methyl orange, methyl red, phenolpthalein. They give a color change when the concentration of an acid as reached a critical limit in order for the reaction to be stopped. These indicators are involved in acid-base titrations, oxidation- reduction reactions and so on. More accurate results of the volume of the required acid or base is obtained by the introduction of these indicators.

Why do the inner walls of a vacuum flask have a silver coating?
Citrus2011 [14]

<u>Answer</u>:

The inner walls of a vacuum flask have a silver coating to reduce heat loss by radiation.

<u>Explanation</u>:

The vacuum flask has an inner silver lining to prevent the transfer of  heat by radiation. Radiation is a process where the emission or transformation of energy happens in the form of wave or the  particles through the material medium.

Vacuum flask being working as thermal insulator helps in maintaining the substance its actual temperature for a long time. The silver lining acts as a reflector .It  prevents the heat radiation to released out of the flask.
