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.

Why refraction does not occur in opaque medium?
Refraction is the bending of the rays of light when it travels from one medium to another... For refraction to occur there should be some difference in the refractive index of the materials.... Refraction can also occur in Opaque medium........

Pure substance definition?
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Why must an indicator indicate for one substance only?
An indicator does not need to indicate for only one substance. Depending on the field, sometimes it does and sometimes it does not. If it is a drug test where an artificial drug is similar to a natural substance, then an indicator should test for just the illegal substance. In a mine, a number of valuable chemicals are found together. In that case a broad test can be used. You do not care if the chemical reaction shows if any of the desired chemicals are present. If the test is positive, you want to mine the ore. If it is negative, you will save your money.

How you would determine that the distilleate collected is a pure substance?
Pure Substances Boil at a Constant Temperature while Mixtures do not, To determine if the Distillate is pure the Liquid distillate would be boiled and for example if the substance is water, it should begin boiling at exactly at 100 degrees celcius if it boils below or above that point it is not a pure substance

It should be opaque
What are the advantages and disadvantages of using a pH strips?
Advantages to using pH strips is that the user does not have to determine which indicator to use for a sample, they are inexpensive and it's a faster way to receive results than using indicators. Disadvantages to using pH strips is that the accuracy is lower and the solution should be only clear and colorless.
