Why is it that the presence of indicator does not affect reaction between acid and base?
Indicators do not interfere with the reaction between an acid and a base because they are typically weak acids or bases themselves. They only change color depending on the pH of the solution but do not participate in the acid-base reaction. This allows the reaction between the acid and base to proceed as normal.
What are some examples of acid base activities that can be used to teach students about chemical reactions?
Some examples of acid-base activities that can be used to teach students about chemical reactions include: Mixing baking soda and vinegar to observe the fizzing reaction. Testing the pH of different household substances using pH paper or indicators. Conducting a titration experiment to determine the concentration of an acid or base. Demonstrating the neutralization reaction between an acid and a base using indicators like phenolphthalein.
Indicators used in acid base titration?
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
What is the difference between a redox indicator and an acid-base indicator?
Redox doesn't use indicators. It uses the natural colouration of the chemicals involved to determine the endpoint and titre. Acid-base titrations use a pH indicator, as otherwise there is often no way to tell the difference between an acidic solution and a basic one.
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 are acid-base indicators?
Acid-base indicators, are chemicals that change color in response to acidic or basic conditions.
What are the household use of acid-base indicator?
common household indicators of acid base
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
What are acid base indicators?
These indicators are substances which change their color depending upon acidity/basicity of the solution.
what acid-base change color when in contact with an acid or a base?
pH indicators change the color in contact with acids or bases.
Why is it that the presence of indicator does not affect reaction between acid and base?
Indicators do not interfere with the reaction between an acid and a base because they are typically weak acids or bases themselves. They only change color depending on the pH of the solution but do not participate in the acid-base reaction. This allows the reaction between the acid and base to proceed as normal.
Is flammability a example of chemical property?
Yes, because it shows you the difference between an acid or a base. An of course its both an acid and a base?
What is the Chemical name for an acid base indicator?
there are many types of acid base indicators - see chart at http://chemistry.about.com/library/weekly/aa112201a.htm Common indicators: Methyl orange - acid=red, base=orange Bromcresol green - acid=yellow, base=blue Bromphenol blue - acid=yellow, base=blue Phenolphthalein - acid=colorless, base=red it is also easy to use litmus paper - acid=red, base=blue
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 is status indicators?
indicators are a slip of paper that detects wether a substance is an acid or a base, but having the paper change colors
Is a indicator an acid or base?
Yes, indicators are one or the other of those things.
Is an indicator base or acid?
Yes, indicators are one or the other of those things.
