What are some indicators?
Indicators are chemicals that change color in the presence of an acid or a base. The most commonly used indicator is phenophthalein.
What are the indicators in iodometry?
Indicators commonly used in iodometry include starch, which forms a blue-black complex with iodine, and potassium iodide, which reacts with iodine to form a yellow-brown color. These indicators help in detecting the endpoint of the iodometric titration.
What substance is used as an acid-base indicator?
Phenolphthalein, Metyl Orange, Methyl Red, Thymol Blue and Bromothymol Blue are some of the commonly used acid-base indicators. The property of such indicators should be the capability of showing a distinct chemical change with respect to a particular pH value.
What is commonly used natural indicator?
natural indicators can be used to detect whether a given substance is an acid or base.It can be easily available in our homes too. And you can prepare it too.They do not have harmful affects .so they should be used instead of chemical indicator which may some time be harmful.
What are absorbing indicators?
Absorbing indicators are substances that can absorb light at a specific wavelength and then emit light at a longer wavelength. These indicators are commonly used in chemistry for analyzing the presence or concentration of certain compounds in a solution based on the color change they produce.
What is commonly use indicator?
commonly used natural indicator include indicators used mainly at our homes, labs and laboratories . natural indicators are obtained from plants. RED CABBAGE ONIONS LITMUS CURRY POWDER TURMERIC POWDER CHERRY TAMARIND GRAPES GERANIUM PETALS CARROT MORNING GLORY PETALS PEAR
What detects acids and alkalis?
Indicators are substances that change color in response to the presence of acids or alkalis. pH meters and pH papers are commonly used to detect the acidity or alkalinity of a solution based on the color change of the indicator.
What are two commonly used indicators are bromthymol blue and?
Two commonly used indicators are bromothymol blue and phenolphthalein. Bromothymol blue is typically used in acid-base titrations, changing from yellow in acidic solutions to blue in alkaline conditions. Phenolphthalein, on the other hand, is colorless in acidic solutions and turns pink in alkaline environments, making it another popular choice for similar applications. Both indicators help visualize pH changes during chemical reactions.
What is the chemical used to identify changes in pH?
The chemical commonly used to identify changes in pH is an indicator, such as litmus paper or phenolphthalein. These indicators change color in response to changes in the acidity or alkalinity of a solution, allowing for easy visual detection of pH changes.
Is neon in high voltage indicators?
Yes, neon gas is commonly used in high voltage indicators because it emits a bright orange-red light when electricity passes through it, making it visible even in daylight. This makes neon indicators effective tools for displaying when high voltage is present.
What are some indicators of acids?
Methyl Red, methyl orange, bromophenol blue, phenolphthalein, thymolphthalein, bromocresol green, bromothymol blue are all used as acid base indicators.
What can indicators identify?
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
