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.

Ph-indicator?
A pH indicator is a substance that changes color based on the acidity or basicity of a solution. It is often used in chemistry experiments to determine the pH of a solution. Common pH indicators include litmus paper, phenolphthalein, and universal indicator.
What is the colour with universal indicator smelling salts?
The color of universal indicator in smelling salts can vary depending on the specific chemical composition and pH of the salts. However, typically smelling salts with universal indicator will change color to indicate the presence of ammonia gas, which is often associated with a blue or green color change in the indicator solution.
What name is given to a substance which changes colour in acids and alkali's?
A substance that changes color in acids and alkalis is called an indicator. These are often used in laboratory settings to determine the pH of a solution based on the color change it undergoes when exposed to different levels of acidity or alkalinity.
What color is pH 4?
To the best of my knowledge, it should be colourless. Lone pairs and conjugation are often attributed to giving colour, so any colour observed will likely be due to other ions in solution
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.

Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.

Explain the work of phenophthaline and litmus paper?
It is an acid - base indicator. Often used in titrations, it turns colorless in acidic solutions and pink in basic solutions.. litmus paper color... Red in acidic solution n blue in alkaline solution

How does the color change when a strong acid is added an alkali to neutralise?
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
What is colour with universal indicator of kitchen cleaner?
The color of a universal indicator when mixed with kitchen cleaner typically depends on the pH level of the cleaner. Most kitchen cleaners are alkaline, often resulting in a color change to blue or purple on the universal indicator scale. This indicates a pH level above 7, suggesting the cleaner is effective for cutting grease and removing stains. Always refer to the specific product’s pH for precise identification.
What is a water colour with universal indicator?
A watercolour with a universal indicator is a solution that includes a pH indicator that changes color depending on the acidity or alkalinity of the water. Universal indicators typically range from red in acidic conditions (pH < 7) to green at neutral (pH 7) and blue/purple in alkaline conditions (pH > 7). When mixed with water, this indicator provides a visual representation of the water's pH level, allowing users to assess its chemical properties easily. It is often used in educational settings to demonstrate pH testing and the effects of different substances on water quality.
How can a pH indicator be useful?
pH indicator works as the range by alkalinity wether it's basic or acidic. Indicator properties are often found naturally in plants (eg. litmus). pH indicators are often just refined versions of various natural plant chemicals or synthesized versions of them.
Water is often called the universal?
The universal solvent
