What is a universal indicator changes into this color in water?
It will go green around pH 7. However because you are using universal indicator, it will be difficult to establish whether your water is completely neutral due to the variation in 'green color.' For example: one person's green could be yellow-green, another person's could be grass colored. x
Is mixing universal indicator and corn starch a chemical change?
Mixing universal indicator and corn starch is primarily a physical change rather than a chemical change. The universal indicator will change color based on the pH of the solution, while corn starch remains unchanged in composition. However, if the mixture is heated or undergoes a reaction that alters the starch, then a chemical change could occur, but simply mixing them does not constitute a chemical change.
Which indicator could be used to identify a neutral solution?
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.
How half titration could be done using only an indicator solution without PH?
In a half titration, you can use an indicator solution without needing to measure pH by adding the indicator directly to the reacting mixture and observing the color change. This can help you identify the endpoint of the titration, where half of the analyte has been neutralized. The color change will indicate the completion of the reaction, signaling that half of the titrant has been added.
Could sixth graders identify different colas?
honestly what kind of question is this? what do you mean? could they identify different cola cans? flavor? what?

Why is the universal indicator more useful than the red cabbage?
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.
Is mixing universal indicator and corn starch a chemical change?

The universal indicator will change color based on the pH of the solution, while corn starch remains unchanged in composition. However, if the mixture is heated or undergoes a reaction that alters the starch, then a chemical change could occur, but simply mixing them does not constitute a chemical change.
What indicator's could be used to produce a color change at both PH 2 and PH?
thymol blue,cresol red,and universal indicatior
What colour does universal indicator turn if you add vinegar?
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
How can you tell if its an acid?
Add an alkali substance to it, such as chalk, if it is an acid it will "fizz" and release carbon dioxide. You could also test with Litmus Paper or Universal indicator.
What are the disadvantages of universal indicator?
they are too expensive to get hold of
How could you test for an acid or alkali?
To test for an acid, you can use pH paper or a pH meter to measure the pH level of a solution. Acids will typically have a pH below 7. To test for an alkali, you can use universal indicator paper which will change color depending on the pH of the solution. Alkalis typically have a pH above 7.
Which indicator could be used to identify a neutral solution?
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.
What scientists are used for mining diamonds?
The science involved in diamond mining is geology: a geologist would identify the indicator minerals in a volcanic pipe that could signal the presence of diamonds.
How do you test for alkaline?
You could test the pH of the substance with UI (universal indicator) paper, or some other indicator. If the pH is <7 or the paper is red/orange/yellow, then its acidic. If the pH is >7 or the paper is blue/purple, then its alkaline. In-between is neutral (green).
How a mixture of methyl orange litmus and phenolphthalein could be used as a type of universal indicator?
A mixture of methyl orange, litmus, and phenolphthalein can be used as a universal indicator because each indicator covers a different pH range. Methyl orange turns red in acidic solutions, litmus turns red in acidic solutions and blue in basic solutions, and phenolphthalein turns pink in basic solutions. By observing the color change of the mixture, you can determine the approximate pH of the solution being tested.
