Does citric acid turn red using a universal indicator?
Citric acid typically does not turn red when tested with a universal indicator. Citric acid is a weak acid and will likely show a color close to neutral or slightly acidic on the indicator scale.
How is the pH of a solution is measured using universal indicator?
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).
What colour does universal indicator turn if you add vinegar?
Because oven cleaner contains Sodium Hydroxide (Na OH), a 'strong' alkali/base, to dissolve the grease, it would change Universal Indicator a deep blue/purple colour.
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.
What is an advantage of using a universal indicator to test the pH compared to using litmus paper?
A universal indicator covers a broader pH range compared to litmus paper, which only gives a rough indication of acidity. Universal indicators provide a more accurate and detailed measurement of pH levels.

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.
How do scientists measure food pH?
Through using the universal indicator or the PH probe.

How do you test of acids an bases?
using an universal indicator, or you can use litmus paper or a pH meter.
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.
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.
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.
