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 else can I help you with?
When some aci is added to a solution of an alkali will the pH value of the solution increase or decrease explain?
When an acid is added to a solution of an alkali, the pH of the solution will decrease. This is because the acid will increase the concentration of hydrogen ions, leading to a more acidic solution.
Explain the functions of solution A and solution B?
The function of solution A and B is to have a color change to cherry red if nitrites are present in the product.
What is pseudo buffer?
A pseudo buffer is a theoretical construct used in computer science to explain certain algorithms or data structures. It is not an actual buffering mechanism, but a conceptual idea to simplify the explanation of complex systems.
Will the solution of potassium chloride and water conduct electricity or not explain?
Yes, a solution of potassium chloride and water will conduct electricity. When potassium chloride (an electrolyte) dissolves in water, it dissociates into potassium ions and chloride ions which can carry electric current.
If dish of sugar and water solution is left in the sun after a few days the solution has disappeared and a white residue remains on the dish Has a physical or chemical change taken place explain?
Yes, A physical change has taken place. The water has evaporated and left the sugar. Neither substance has changed its identity. GOOD LUCK ON YOUR TEST!
