Is the universal indicator or phenolphthalein is more accurate?

THe universal indicator is more accurate as it can detect different ranges in the pH, whereas phenolphthalein only changes at a ph of 8.0

What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
Why is the universal indicator better than other indicators?
Because universal shows how strong or weak a substance is. Litmus just shows if its Alkaline or Acid. ps a 12 yr old wrote this.
Which is more polar bromophenol blue or phenolphthalein?
phenolphthalein
Is a universal indicator a mixture of 4 different indicators?
no it is more than 4
A substance that directly determines the acidity or alkalinity of a fluid?
Use a universal indicator or litmus paper. Litmus paper will turn red in acidic conditions and blue in alkali conditions. Universal indicator can give a more accurate PH reading than litmus paper.

Is universal indicator always the best indicator?
No, not always. Some indicators are better suited for certain ranges; UI will provide a rough indication across a huge range, but other indicators can be more accurate across a small range, and this is when they are used.
What is the specific name of universal indicator?
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
Which is more polar bromophenol blue or phenolphthalein?
phenolphthalein

Why universal indicator is more costly than litmus?
I suppose that the preparation procedure is more difficult.

When phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
What is the difference between a universal indicator and a pH meter?
A pH meter is an ion selective electrode (H+), it gives pH to a far more accurate figure and leaves no room for interpretation (based on wetness of strip, colour may appear to show different pHs with univ. indicator
How do you test pH levels of water?
Universal indicator or litmus paper are the most common methods. You can get pH paper...the color of the paper correlates to certain pH's. pH paper is more accurate than litmus paper.
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.
