What pH indicator should the scientists use?
Scientists should consider using universal pH indicator because it can provide a wide range of colors to indicate different pH levels.
What is used to determine the pH of acid and bases?
A pH meter or pH indicator paper is commonly used to determine the pH of acids and bases. pH meters provide a numerical measurement of pH, while pH indicator paper changes color based on the pH level to give a visual indication.
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.
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 are the advantages and disadvantages of measuring pH of lemon juice with indicator solution?
pH paper and MetersAdvantages:1. They give you a numerical value of the pH2. pH meters can give you the exact pH3. They give you an idea as to how acidic and basic the substance isDisadvantages:1. They are too expensive2. pH papers only give you a rough estimate3. pH meters need to be calibrated

How you can test the pH of solution?
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
What are some ways to determine the pH of a liquid?
Some ways to determine the pH of a liquid include using pH test strips, pH meters, or pH indicator solutions. pH test strips change color based on the acidity or alkalinity of the liquid, pH meters provide a numerical pH value, and pH indicator solutions change color to indicate the pH level.
How does the type of indicator affect the pH?
Each indicator has a specific change of color when the pH is changed.
Name the three most common ways of measuring pH?
The three most common ways of measuring pH are using pH meters, pH test strips, and pH indicator solutions. pH meters provide the most accurate and precise measurements, while pH test strips are convenient and easy to use. pH indicator solutions involve adding a few drops of a chemical that changes color based on the pH level of the solution.
How can a person distinguish among acids bases and neutral substances?
With a pH meter or pH paper. Other indicator dyes (e.g. litmus, phenolphthalein) may be used if it is not necessary to determine the exact numerical pH value.
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.
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.
