What else can I help you with?
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.
Situation where you might use the iodine colorimetric test?
You might use the iodine colorimetric test to detect the presence of starch in a solution. Iodine reacts with starch to form a blue-black complex, allowing for easy visual identification of the presence of starch. This test is commonly used in biology and food science laboratories.
Can you use a chlorine test strip to test the acidity in your spit?
No, chlorine test strips are designed to measure the concentration of chlorine (such as in a swimming pool). To test the acidity in your saliva, you would need to use a pH test strip specifically designed for measuring pH levels.
What color tube would you use for a AST test?
For an Aspartate Aminotransferase (AST) test, you would typically use a red-top tube, which does not contain any anticoagulant. This allows the blood to clot, separating the serum that is needed for the test.
What would you use to test a gas to see if it was water vapour?
I would probably test it as a liquid using a pH test to see if it comes up as pH 7 (neutral, which is what pure water should be). To do this, though, try trapping the gas in a jar and with the lid on, put that jar in ice until it all condenses, then pH test the condensation. :)
What would an organism use for energy in test tube during fermentation and what color would the indicator be.?
Sugar is the energy source, the definition of fermentation is: The anaerobic conversion of sugar to carbon dioxide and alcohol by yeast. As to the color of the indicator it would depend on what you were using to test and what you were testing for (sugar, Co2, alcohol).
What substance is used to determine the presence of an acid or base?
by using an indicator like litmus paper!!!
What is a litmus paper and how to use it?
A litmus paper is a indicator that is used to test for acids or bases
How do you test of acids an bases?
using an universal indicator, or you can use litmus paper or a pH meter.
What liquid do you use to test the pH scale?
A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.
Why was universal indicator paper used to test the pH rather than placing universal indicator solution into the mixture?
Use of paper avoid the contamination of the sample.
Is it advisable to use just one type of indicator to determine the nature of an unknown solution?
No; every test must be confirmed by another test.
What type of indicator should be used to determine the pH of an opaque substance?
Indicators would work to determine the pH of colored substances. The color change may be difficult to read depending on the indicator used. Another alternative to adding a indicator to the substance would be to use a test strip.
What is a good forex indicator one can use?
A good forex, or also known as FX indicator to use while in the market would be the FCCal indicator. From popular consumer reviews, it helps prevent trades during a news report.

What equipment would you use to grind up red cabbage to make an indicator?
You can use a blender or food processor to grind up red cabbage to make an indicator solution. Make sure to strain the mixture to separate the liquid from the solids. The liquid will then be ready to use as a pH indicator.
In a pH test how much wide range indicator to use for 5 ml?
A pH paper can be used also for a small sample.
