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
Which indicator could be used to identify a neutral solution?
there is no such indicator.the only way is to add the acidic and basic indicators ,if it does not change the colour of the solution then it is neutral.
How do you make a pH indicator not using red cabbage?
A pH indicator can be made out of grape juice or beetroot or even eggplant. Grate 1/4 cup of beetroot or eggplant into 2 cup water, boil for 10 min and strain for the dark liquid, by the way grape juice could be used right out of carton. Add indicator to the substance that is being tested, it will be more red for pH of 2 and greener for pH of 12, and test for better knowledge of all colors that pH indicator can turn.

honestly what kind of question is this? what do you mean? could they identify different cola cans? flavor? what?
Why do liquid conducts electricity?
the liquid could be a metal such as mercury or gallium.the liquid could be a polar solvent such as water and contain ionsany surface whether it be a solid or a liquid will conduct an AC current.
How could you test for an acid or alkali?
Litmus; universal indicator; reaction tests; spectroscopy.

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.

What indicator's could be used to produce a color change at both PH 2 and PH?
thymol blue,cresol red,and universal indicatior
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.

Do you need to have water present to see if something is an acid or an alkali?
hi im just starting a level chemistry and i am not aware that you need water to find out if something is acid or alkali, you could use a indicator such as universal indicator or methyl orange and so on, or you could use indicator paper. If this helps good, if not sorry. Jack
What are the disadvantages of universal indicator?
they are too expensive to get hold of
What are properties could be used to identify an unknown material?

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.
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.
