How do you find the pH of a substance?
You use a litmus indicator.
An indicator does which one of the following in the presence of acids and bases?
Indicators can be used to determine if a substance is a acid or a base because of the reaction that occurs between the substance and the indicator. This creates a color change in the indicator (depending on which indicator you use). If it is a universal indicator, the substance may change from deep red to violet. If it is a litmus indicator, it will only turn either red or blue.
How does a chemical indicator work?
a chemical indicator lets you determine the equivalence end point that's only when the reaction takes place
What are three substances that determine if a substance is acidic or basic?
universal indicator will give you the PH of a substance no matter what PH it, phenolphthalein will turn pink in an acidic solution and will remain colourless in a basic or litmus paper which will turn blue in basic conditions and red in acidic conditions. alternatively you could just use a digital PH meter

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 can you use to make a MODEL of a sperm?
You could use any light-weight modeling substance, or you could carve one out of thick styrofoam.
How can you test is a substance is an acid base or neutral?
You would have to use a special paper called litmus paper. It comes in red and blue. If a substance is a base, it will turn the red litmus paper blue. If it is an acid, it will turn the blue litmus paper red. You can also use red cabbage as an indicator, too. If you want to find the pH of a substance, use a wide-range indicator and a pH measurement.
What could be the background research for which one can be use as an acid base indicator red cabbage or red beet?
