The pH of a solution is measured using universal indicator by adding a few drops of the indicator to the solution and observing the color change. The color of the solution corresponds to the pH level on the universal indicator color scale, which ranges from red (acidic) to purple (neutral) to blue (basic).

How to check pH value using universal indicator?
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.
How can the pH of a solution be measured?
pH can be measured using a pH meter, pH strips, or pH indicator solution. A pH meter provides a numerical value for pH, while pH strips or indicator solution change color based on the pH of the solution being tested.
What is the purpose of using universal indicator in titration?
Universal indicator is used in titration to indicate the pH of a solution being titrated. It changes color in response to changes in the pH of the solution, helping the observer to determine the endpoint of the titration when the reaction is complete. This allows for a more precise determination of the amount of titrant required to reach the endpoint.
What colour does citric acid turn when using a universal indicator?
Citric acid typically turns red when using a universal indicator, indicating that it is acidic.
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.

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.
How do you indicate that a solution is a alkaline solution or a base?
By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you>>>:)d
You can find the pH of a substance by using?
using a pH meter or pH indicator strips, which change color depending on the acidity or alkalinity of the substance. Another method is using universal indicator solution that changes color at different pH levels, allowing you to estimate the pH of the substance based on the color observed.
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.
3 How is the Universal indicator color chart used to measure acidity?
We measure pH by using a pH scale which has different colours on it which indicates the liquid. Universal indicator is a pH indicator that transitions through numbers 1- 14 (on a pH chart) to indicate the acidity or alkali of solution. A pH meter is an electric instrument used to measure the pH of a liquid which might be an acid neutral or an alkali. and there is my answer Lewis Jones park community school lots of substances change colour at specific pH values, so you have to use a colour chart for that specific substance. Universal indicator is a mixture of lots of different indicators so it changes colour many times throughout the entire pH range, and you can compare it to the universal indicator colour chart to find how acidic or alkaline your substance is.
How you can conclude the pH value of a fabric?
we can conclude by using a ph paper or universal indicator.
