How bicarbonate indicator show present of oxygen or not?
if oxygen present the colour of bicarbonate indicator will change to brown like in my experiment,i think it's not fully successful but not dissapoint me.
What is colour of ethanol in universal indicator?
Universal indicator changes color in different pH ranges. In the case of ethanol, which is pH-neutral, universal indicator would likely show a green color.
What colour would universal indicator show in an aqueous solution of sugar and why?
The universal indicator would likely show a green color in an aqueous solution of sugar. This is because sugar is a neutral compound and does not significantly affect the pH of the solution, resulting in a green color indicating a neutral pH.
What is the difference between an indicator and a universal indicator?
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.
Which indicator would be the best to show a change from an acid to a base?
A pH indicator like litmus paper can best show a change from an acid to a base. Litmus paper is red in acidic solutions and blue in basic solutions, making it easy to visually detect the shift in pH.
What colour would the indicator with orange juice?
The indicator's color when mixed with orange juice would depend on the specific pH indicator used. For example, phenolphthalein would remain colorless, while bromothymol blue would turn yellow due to the acidic nature of orange juice. Generally, many indicators would show a shift towards a yellow or pink hue, indicating acidity.
What colour does the univeral indicator turn in ammonia solution?
It depends on the concentration of the ammonia solution as the universal indicator can show a huge variety of colors.
If your head gasket has gone on your A140 would the dipstick show clear oil on it or would it be a different colour?
When oil and water are combined in the engine it will form a white frothy mixture which will be evident on the dipstick. Definate indicator of a blown head-gasket
How do pH indicator dyes show a change in pH from acidic to basic or vice versa?
Certain indicators only change colour when placed in a particular pH level or range (e.g. litmus) and others are colourless in certain conditions (e.g. phenolphthalein, leuchomalachite green's second transition).
What do you call a substance which is used to show changes in pH by its change in color?
An indicator. It is a substance that changes color in response to a change in pH, making it a useful tool in chemistry to visually determine the acidity or basicity of a solution.
What is indicator which has no color with the acidic medium?
Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
