Can Dex-Cool antifreeze be replaced by universal antifreeze?
yes, but you need to get rid of all of the dex-cool first... needs flushed really really good then you can replace the cool with normall cool (green). Now there are some Universal Antifreeze that will mix with dex-cool. that coolant says on the bottle ANY COLOR, ANY MAKE, ANY MODEL....
What are color forces in terms of quarks the fundamental particles?
The color force is another term for the strong nuclear force. (It doesn't have anything to do with actual colors.) Basically, the color force is the force binding two (or more) quarks together; it's mediated by the exchange of gauge particles called gluons. A quark will change color from, say, "red" to "green" by emitting a red-antigreen gluon, which can be absorbed by a "green" quark (which will then change to "red").
What color did universal indicator if it is added to weak alkali?
blue
What color is the color of universal indicator?
they have so many colours because they show if it is an acid or an alkali
How are indicators used to detect acids and alkalis?
Indicators (for example LITMUS PAPER) can detect whether a certain liquid is an acid or an alkali. Litmus Paper turns red when dipped in an acid, blue in an alkali Universal Indicators have show how strong or weak and acid or alkali is.
When you put an alkali and Universal Indicator in a test tube what colour does it go?
When an alkali is added to a test tube containing Universal Indicator, it typically turns the indicator solution a dark green or blue color. This is because Universal Indicator is a mixture of different pH indicators that show a range of colors from red (acidic) to green (neutral) to blue or purple (alkaline). The specific color change observed may vary depending on the concentration and type of alkali used.
What color does the indicator paper turn if the substance is a strong acid?
If you are testing with Universal Indicator or the Litmus Test it will turn red.
How can hydrochloric acid turn red in color?
Universal Indicator turns concentrated HCl red because Universal Indicator turns strong acids reds.
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.
What color does universal indicator turn in deionized water?
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
What color does Universal indicator turn in diluted hydrochloric acid?
Hydrochloric Acid is known to be a very strong acid. A 0.01 molar solution of HCl has a pH of 2 ( -log(0.01) ) which on the pH scale is very acidic (under 7 is acidic, 7 is neutral, over 7 is basic). On a universal indicator test, HCl would come out as red. A basic solution would be a more blue-green, or green depending on the concentration.This is a color chart for a universal indicator test:http://chem.csusb.edu/images/pH_chart.gif
What does universal indicator test for?
A universal indicator changes color in response to the pH of a liquid. Do determine the pH of the liquid, you need to refer to a color chart that tells you which color indicates which pH.
How does the color change when a strong acid is added an alkali to neutralise?
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
What color does borax turn in Universal indicator?
Blue
