What is an indicator and what is its purpose?
Indicator (distance amplifying instrument) In various contexts of science, technology, and manufacturing (such as machining, fabricating, and additive manufacturing ), an indicator is any of various instruments used to accurately measure small distances and angles, and amplify them to make them more obvious.

- Find the right supporting data.
- Determine the right measurement methodology and frequency.
- Assign ownership for your KPIs.
- Ensure KPIs are understood by people within your organisation.

What are some examples of an indicator?
there are two types of indicators are found in chemistry: (1) Natural Indicators (2) Artificial Indicators What are two examples of indicators? Red Cabbage, Cherries, Turmeric are examples of natural indicators while phenolphthalein, methyl orange, and litmus paper are examples of synthetic indicators. What is the most common indicator?
What is the role of indicator in the process of titration?
The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
What is indicator and its use?
Indicators are substances which show a change in colour when brought in contact with acids and bases. The most common indicator used in the laboratory is the litmus. It is extracted from lichens and is available either in the form of solutions or in the form of strips of paper known as litmus paper.
What is the role of an indicator in an acid-base reaction?
Acid-base indicators are most often used in a titration to identify the endpoint of an acid-base reaction. They are also used to gauge pH values and for interesting color-change science demonstrations.
What is the role of an indicator in a reaction multiple choice?
Answer: To show when the reaction has reached or past the equivalence point.
What is an indicator answer?
An indicator is a substance that changes its colour in acidic and basic medium.An indicator shows one colour in acidic medium and different colour in basic medium so that they are called indicators. lndicators derived from natural sources are called natural indicators.
What is an indicator for Class 7?
CBSE NCERT Notes Class 7 Chemistry Acids, Bases and Salts. Substances that are used to indicate whether a substance is acid or a base are known as indicators. They change their colour on addition of a solution containing an acidic or a basic substance.
What is an indicator Class 10?
Indicators: Indicators are those substances which tell us whether a substance is acidic or basic by change in colour. For e.g., litmus solution.
What is an indicator in science?
Indicators are substances that change colour when they are added to acidic or alkaline solutions. Litmus, phenolphthalein, and methyl orange are all indicators that are commonly used in the laboratory.
What is an acid indicator?
Acid - Base indicators (also known as pH indicators) are substances which change colour with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions. Consider an indicator which is a weak acid, with the formula HIn.
What are the characteristics of indicators?
Characteristics of good indicatorsValid: accurate measure of a behaviour, practice, task that is the expected output or outcome of the intervention.Reliable: consistently measurable over time, in the same way by different observers.Precise: operationally defined in clear terms.More items...•
Answer
the purpose of an indicator is to test how acidic or basic something is.
Answer
The role of an indicator is to establish the equivalence point when two substance has reached its neutralization process.
What is an indicator in a group?
An indicator is a segment of information that gives a sense of the direction to the information — such as whether the feeling of hope is greater or less than in the same time in the previous year.
Why do we need indicators in a project?
In project planning; indicators form the link between theory and practice. An indicator is a tool to help you to know whether your work is making a difference.
What are indicators that tell us what we have planned?
Indicators that tell us whether the activities and actions we have planned are actually happening as intended are known as Output Indicators . These types of indicators will help you to monitor whether you are doing what you planned (outputs) but do not give us an idea of the effect that is brought about by these outputs. That is why it is important to monitor both the implementation of our actions and the changes that we think are being produced as a result – positive or negative, intended or unintended.
What are quantitative indicators? What are some examples?
Examples of Quantitative Indicators can be: 1 The number of people attending a training 2 The weight of fish caught 3 Unemployment (By age, gender, Occupation) 4 Per Capita Income 5 No. of Community Organizations 6 Rates of HIV Infection 7 The average rice harvest per hectare 8 The cost of transport to market 9 Increase in household income 10 Infant Mortality Rate
What are some examples of qualitative indicators?
Examples of Quantitative Indicators can be: The number of people attending a training. The weight of fish caught.
What is the function of an indicator in a titration process?
Follow Us: The function of an indicator in a titration process is to determine the equivalence point when two solutions have reached neutralization. An indicator can either be internal or external. An internal indicator is mixed in with the reactants and typically provides a visual prompt, while an external indicator is an electrochemical apparatus.
What are some examples of pH indicators?
Common examples of pH indicators are methyl orange, methyl red, phenol red and phenolphthalein. An observable color change indicates that the reaction is nearly or completely neutralized.
