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.

Why is universal indicator often more useful than litmus indicator?
Universal indicator can show a wider range of pH levels compared to litmus indicator, which can only indicate acidic or basic solutions. Universal indicator provides a full spectrum of colors corresponding to different pH values, making it more precise and versatile for measuring pH levels in various solutions.
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.
Universal indicator is mostly preferred over litmus indicator why?
Universal indicator covers a wider pH range compared to litmus indicator, which only detects acidic or basic conditions. Universal indicator provides a more precise indication of the pH level of a solution by producing a range of colors across the pH scale.
How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
Is the universal indicator or phenolphthalein is more accurate?
Universal indicator is generally considered more accurate than phenolphthalein because it provides a broader range of colors to indicate the pH of a solution across a wider pH range. Phenolphthalein is more limited in its pH range and color changes.

Why do you grind the cabbage other than just stir it for the universal indicator?
Grinding the cabbage helps to break down the cell walls, which releases more of the pigments and compounds responsible for its color. This increases the concentration of the anthocyanins, making the extraction more effective. Stirring alone would not achieve the same level of pigment release, resulting in a less accurate or vibrant universal indicator. Thus, grinding enhances the extraction process, ensuring a better visual representation of pH changes.
How much does universal indicator cost?
The cost of universal indicator can vary depending on the brand, quantity, and supplier. On average, a small bottle of universal indicator can cost around $5-$10. Larger quantities or more specialized versions may be more expensive.

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.
Why do you use hot water when making indicator from red cabbage leaves?
because you get more colour

Is a universal indicator a mixture of 4 different indicators?
A universal indicator is a mixture of several indicators, typically about 10, that have different colors at different pH levels. This mixture allows the universal indicator to display a different color for each pH level across the entire pH scale.
