To check pH value using universal indicator, you can add a few drops of the indicator to the solution you want to test. The color it turns will indicate the approximate pH of the solution based on the color chart provided with the indicator. Match the color of the solution to the chart to determine the pH value.

Why is it difficult to measure the pH value of household bleach using universal indicator?
Household bleach is a strong base, typically with a pH of around 11-13, which is outside the color range of universal indicator, making it difficult to accurately measure its pH using this indicator. Universal indicator is more useful for measuring pH in the neutral to slightly acidic range. To accurately measure the pH of bleach, a pH meter or pH paper with a broader range would be more suitable.
Why is it difficult to measure pH value of household bleach using universal indicator?
Household bleach is a strong alkaline solution, making it difficult to accurately measure its pH using universal indicator. Universal indicator is more suited for measuring pH in the neutral to slightly acidic range, and may not provide an accurate or precise reading for highly alkaline substances like bleach. A pH meter or specific alkaline pH indicator may be more suitable for measuring the pH of household bleach.
What is one limitation of universal indicator paper?
One limitation of universal indicator paper is that it may not provide a precise numerical pH value but rather a color change indicating a range of pH levels.
What is the pH value of universal indicator?
When it is not mixed with any other solution, it is green. Green represents neutrality, so its pH is 7.
What can be used to get a pH value?
A pH meter or pH test strips can be used to measure the pH value of a solution. pH meters provide a numerical value of the pH, while pH test strips change color based on the pH level of the solution, allowing for an approximation of the pH value.
How you can conclude the pH value of a fabric?
we can conclude by using a ph paper or universal indicator.

What is the pH value of toilet cleaing acid?
Just test it with universal litmus paper or universal indicator(liquid)
How can you find the intensity of the color given the pH value?
use universal indicator

What does yellow indicate on the ph scale?
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
If a few drops of universal indicator is added to water changes red what pH value is it?
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.
Why is it difficult to find the pH value of blackcurrant juice using universal indicator?
Well, Blackcurrant juice would be seen more of an actual indicator than a solution. I suggest you use a different solution that has a higher acidic or alkaline scale.
What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
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.
