Antacids are basic substances: a blue color.
The Universal Indicator would go green which is pH 7.
A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.
Methyl Orange is red in an acidic solution.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
A neutral solution will have a pH of 7. One indicator that can be used to identify a neutral solution is litmus paper, which will remain its original color (usually blue or red) when immersed in a neutral solution.
A neutral solution added to universal indicator will turn green.
red
The Universal Indicator would go green which is pH 7.
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
It depends on the concentration of the ammonia solution as the universal indicator can show a huge variety of colors.
The color of universal indicator solution for bleach is typically blue or purple, indicating a high pH level.
Universal indicator turns dark blue or purple in a strong alkaline solution.
Universal indicator solution turns a shade of red, orange, or yellow when added to an acidic solution.
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.
A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
