Universal Indicator solution turns yellow in acidic solutions and red in strongly acidic solutions.
Acids turn universal indicator solution red.
The bicarbonate indicator turns from purple to yellow when exposed to a basic solution.
An acidic solution will turn methyl orange pink. Methyl orange is an acid-base indicator that changes color from red to yellow in acidic solutions and from yellow to pink in basic solutions.
Potassium and sodium thiosulfate can turn yellow due to the formation of a colored complex with iodine. When iodine is added to a solution containing thiosulfate, it forms a triiodide ion which has a yellow color. This reaction is commonly used in chemistry as an indicator for the presence of thiosulfate ions in solution.
It indicates that the vegetable has carotene in it.
Acids turn universal indicator solution red.
The bicarbonate indicator turns from purple to yellow when exposed to a basic solution.
A neutral solution will turn universal indicator green.
The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
An acidic solution will turn methyl orange pink. Methyl orange is an acid-base indicator that changes color from red to yellow in acidic solutions and from yellow to pink in basic solutions.
Potassium and sodium thiosulfate can turn yellow due to the formation of a colored complex with iodine. When iodine is added to a solution containing thiosulfate, it forms a triiodide ion which has a yellow color. This reaction is commonly used in chemistry as an indicator for the presence of thiosulfate ions in solution.
It indicates that the vegetable has carotene in it.
ye it is an indicator
An acidic solution will cause bromthymol blue to turn from blue to yellow. This color change occurs due to a change in the pH of the solution, with acidic conditions resulting in the indicator changing to a yellow color.
A neutral solution added to universal indicator will turn green.
Bleach is a basic solution, so it will turn universal indicator to a purple color. This indicates a high pH level in the bleach solution.
It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
