Why does the colour of the solution changes from wine red to blue at the end point?
The color change from wine red to blue is due to the change in pH during the titration. The wine red color reflects the acidic environment, while the blue color signifies the basic end point. This color change is typically seen when using indicators such as phenolphthalein or methyl orange in acid-base titrations.

What colour is made by mixing bromothymol blue and sulphuric acid?
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
One indicator that changes colour in an acid and alkali solution?
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
What colour does BTB get in an alkaline solution?
In an alkaline solution, bromothymol blue (BTB) turns blue.
Bromothyl blue and water were bubbled explain why the solution colour changed?
The solution's color changed because bromothymol blue is a pH indicator that changes color based on the acidity or alkalinity of the solution it is in. When bubbled with water, carbon dioxide from the air dissolves in the water, forming carbonic acid, which lowers the pH of the solution, causing the bromothymol blue to change color.
What is the colour of the copper sulfate solution when zinc granules are added to it?
The color of the copper sulfate solution changes from blue to colorless when zinc granules are added to it. This is because zinc displaces copper in the solution through a chemical reaction, forming zinc sulfate and leaving the solution without copper ions responsible for its blue color.
What is the theoretical achromatic point of salivary amylase?
If we add salivary amylase to any solution ( eg:iodine solution) the colour of solution changes to blue.THE TIME TAKEN BY THE SALIVARY AMYLASE TO CHANGE ITS(iodine solution) COLOUR TO BLUE IS CALLED ACROMATIC POINT OF SALIVARY AMYLASE. ie, the time upto which the solution is colourless and after that it gains blue colour.
What color does Benedict' s solution change in another solution?
The Benedict solution contains Copper ii ion so has blue colour. when this solution is allow to react with aldehydic compounds specially sugars the copper ii ions reduce to cupric oxide so colour changes blue to red or pink.
What colour is made by mixing bromothymol blue and sulphuric acid?

What colour does universe indicator with antacid solution?
The universe as a whole does not have a specific colour. However, in a science experiment, when an antacid solution is added to a universal indicator, it may change colour based on the pH level of the solution. This change in colour signifies the acidity or alkalinity of the solution.
What colour does iodine solution turn when starch is presant?
It turns a dark purple/blue colour
