What is the color of the end point for the titration of the acid?

The color of the endpoint for the titration of an acid depends on the specific indicator used. Common indicators include phenolphthalein (pink at high pH), methyl orange (red at low pH), and bromothymol blue (yellow at low pH). The choice of indicator will depend on the pH range of the acid being titrated.

What are the chemicals used in CIP in Biotech processwhat are there mode of action?

A basic cleaner is the most important CIP cleaning chemical, and is used for removing fats and proteins. The most common ones are Potassium Hydroxide and Sodium Hydroxide. A base wash is often followed by an acid wash to remove minerals and to neutralize the base (the acid washes away with water more easily than the base does). Common acid cleaners in the biotech industry include Phosphoric Acid, Acetic Acid, and Citric Acid.

No. Possibly the most common simple acid would be the hydrochloric acid in your stomach.


How would you select an indicator for an acid-base titration?

Ideally you want an indicator which undergoes its transition somewhere in the range where the pH is changing the fastest; that is, in the most nearly vertical part of the graph of pH vs. volume of titrant added.
