What are the types of compound indicators?

Answer: b. strong base and acid.

What are examples of indicators?

Some examples of indicators are Litmus, turmeric, phenolphthalein, etc. Any material that offers a visual evidence of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution, generally by a colour change are called the chemical indicators.

What is an indicator in Chem?

chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.

What is an indicator name three indicator?

(a) An indicator is a ‘dye’ that changes colour when it is put in an acid or a base. The three most common indicators are: Litmus, Methyl orange and Phenolphthalein.

What is indicator in chemistry and its types?

An indicator is a substance that changes its color in acidic and basic medium. An indicator shows one color in an acidic medium and different colors in a basic medium so that they are called indicators.

What are the 3 types of ionic compounds?

Sodium chloride, potassium phosphate and magnesium sulfate are the three types of ionic compounds.

How many types of indicators are there in chemistry?

Types of Indicators Artificial and Natural indicators are the two types of Chemical indicators. Litmus, red cabbage, turmeric, china rose are a number of the present indicators around us.

What are common types of indicators?

Litmus, phenolphthalein, and methyl orange are all indicators that are commonly used in the laboratory.

What are the different types of indicators used in chemistry?

In addition to pH indicators, there are two other types of indicators used in chemistry. Redox indicators are used in titrations involving oxidation and reduction reactions. Complexometric indicators are used to quantify metal cations. Methyl red is a pH indicator used to identify pH values between 4.4 and 6.2.

Which indicator is used to quantify metal cations?

Complexometric indicators are used to quantify metal cations. Methyl red is a pH indicator used to identify pH values between 4.4 and 6.2. At low pH (4.4 and lower) the indicator solution is red. At high pH (6.2 and above) the color is yellow. Between pH 4.4 and 6.2, the indicator solution is orange.

What are the physical properties of indindicators?

Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor. The pH value of a neutral solution is 7.0. Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic (alkaline).

What is the color of metamethyl red indicator?

Methyl red is a pH indicator used to identify pH values between 4.4 and 6.2. At low pH (4.4 and lower) the indicator solution is red. At high pH (6.2 and above) the color is yellow.
