What are natural indicators which can be used to detect basic solutions?
Natural indicators like red cabbage juice and turmeric can be used to detect basic solutions. These indicators change color in the presence of bases, turning blue or green for red cabbage juice and yellow for turmeric, indicating the basic nature of the solution.
What are the different indicators used in the laboratory?
to test if a solution is acidic, alkaline or basic
What is the colour with universal indicators ammonia?
Universal indicators typically turn blue or green in the presence of ammonia. This color change indicates a basic or alkaline solution.
Do acids effect indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to the acidic or basic nature of a solution. Acids can cause indicators to change color depending on their pH level.
Are indicators acidic or basic in nature?
Indicators can be both acidic and basic in nature, depending on their color change properties in response to different pH levels. Some indicators change color in acidic solutions, while others change color in basic solutions.
How do indicators distinguish acids and bases?
Indicators are substances that change color depending on the pH of a solution. They do this by undergoing a reversible chemical reaction that is sensitive to the concentration of hydrogen ions (H+) in the solution. In acidic solutions, indicators change color to reflect the acidic pH, whereas in basic solutions, indicators change color to reflect the basic pH.
Are indicators acidic?
Indicators are substances that change color in response to changes in pH, indicating whether a solution is acidic, basic, or neutral. Some indicators change color in acidic environments, while others change color in basic environments. The specific indicator used will determine how it responds to acidity.
What are examples of self indicators in chemistry?
Examples of self indicators in chemistry include phenolphthalein, bromothymol blue, and litmus. These substances change color based on the pH of the solution they are in, making them useful for visually determining whether a solution is acidic or basic without needing to add any additional indicators.
What is the effect of onion clove and vanilla on acids and bases?
Onion Clove and Vanilla are Indicators . They indicate if a susbstance is Acidic or Basic in nature by changing their smell . These type of indicators which change smell are known as "olfactory indicators".
Can anybody please tell how to make a natural indicator using vegetables and flowers and test different household items to distinguish them as acidic or alkaline?
Natural indicators : -Red cabbage solution(juice) -Strawberry solution -Cherry solution -Rose solution You can use any of these as an indicator, and you'll get the same result, here's how : after gaining the vegetable/rose juice, drop some of it on any solution and you'll get the results : the purple cabbage juice turns red when it is mixed with something acidic and turns green when it mixes with something basic.
How are pH indicators classified?
pH indicators are classified based on the pH range over which they change color. They can be classified as either acidic, basic, or universal indicators. Acidic indicators change color in acidic solutions, basic indicators change color in basic solutions, and universal indicators change color over a wide pH range.
How can you tell when a solution is alkaline or basic?
A solution is considered alkaline or basic when it has a pH greater than 7. This can be determined using pH indicators, pH meters, or litmus paper. Additionally, alkaline solutions tend to have a slippery feel and can often be identified by their bitter taste.
