What is the color of BTB solution after you exhaled into it?
It turns yellow after we exhaled into the btb solution..:)
What colour does phenolphthalein change to when it reacts with and alkaline solution?
Phenolphthalein changes from colorless to pink when it reacts with an alkaline solution.
If you add indicator to an alkaline solution what will happen?
If you add an indicator to an alkaline solution, the indicator will change color to indicate the basic nature of the solution. Common indicators like phenolphthalein will turn pink or purple in an alkaline solution with a pH greater than 7.
What color is BTB in an acid?
BTB stains hands and clothes. As carbon dioxide is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow.
What colour does universal indicator turn in a strong alkaline solution?
Universal indicator turns dark blue or purple in a strong alkaline solution.

What is the colour change of litmus paper in a basic alkaline solution is?
blue and purple
What is the function of alkaline solution in Biuret's test?
The alkaline solution in Biuret's test serves to denature the proteins present in the sample, breaking down their tertiary structure so that the peptide bonds can react with the copper ions in the reagent. This reaction results in the formation of a purple color, indicating the presence of proteins in the sample.
What color you get after mixing lemon juice to BTB solution?
When you mix lemon juice with bromothymol blue (BTB) solution, the color will change from blue to yellow. This is because the acidity of the lemon juice causes the BTB indicator to shift to its yellow color.
How can pH of a solution be tested?
By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
What will happen if you drink btb solution?
BTB (bromothymol blue) solution is a chemical indicator commonly used in science experiments. If consumed, it can cause gastrointestinal irritation, nausea, vomiting, and potential chemical burns in the mouth, throat, and stomach. It is important to seek medical assistance immediately if BTB solution is ingested.
What color will appear if you add NaOH to BTB?
Adding NaOH (sodium hydroxide) to BTB (bromothymol blue) will turn the solution blue, as the color of BTB changes depending on the pH of the solution. When NaOH is added, it increases the pH, causing BTB to shift from yellow to blue.
Why does adding air from an air pump cause a color change in btb solution?
When air is pumped into a BTB (Bromothymol blue) solution, carbon dioxide in the air forms carbonic acid when it dissolves in the water, lowering the pH and causing the solution to change color. BTB is an indicator that changes color in response to pH changes, shifting from blue in a basic solution to yellow in an acidic solution.
