What indicator uses the acronym 'MA'?
The indicator that uses the acronym 'MA' is Moving Average. It is a widely used indicator used to trade trends.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Is tamarind a indicator?
No, tamarind is not an indicator. Tamarind is a fruit-bearing tree from which a sticky, sour fruit is harvested and used in cooking and traditional medicine. It is not used as a chemical indicator in scientific experiments.
What is a bite indicator?
A bite indicator is a float used by anglers to tell when a fish has taken the bait.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
What can be used as a protein indicator in foods for a science experiment?
Biuret
What can you use in place of bromophenol blue?
Methyl orange or phenolphthalein can be used as alternatives to bromophenol blue in certain experiments requiring a pH indicator. It is important to consider the specific requirements of the experiment and the pH range of the indicator being used.
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
How much phenolphthalein indicator should be used?
Typically, 1-2 drops of phenolphthalein indicator are sufficient to use in an acid-base titration experiment. It is important not to use too much indicator, as it can affect the accuracy of the titration results.
What is the colour and pH of the aqueous solution of universal indicator at the beginning of the experiment?
Green
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Why is phenolphthalein used in the titration experiment?
Phenolphthalein is used in titration experiments as an acid-base indicator because it changes color at a specific pH range (pH 8.2-10.0), making it easy to visually detect the endpoint of the titration when the solution changes from acidic to basic or vice versa. This helps in determining the volume of titrant needed to reach the equivalence point accurately.
What is the best acid base indicator?
One commonly used acid-base indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions. Another popular indicator is litmus, which turns red in acidic solutions and blue in basic solutions. The choice of the best indicator depends on the specific experiment and the pH range being tested.
How bicarbonate indicator show present of oxygen or not?
if oxygen present the colour of bicarbonate indicator will change to brown like in my experiment,i think it's not fully successful but not dissapoint me.
Why did we use bromthymol blue in this experiment?
Bromthymol blue was used in the experiment as an indicator to monitor changes in pH. It changes color in response to pH changes, turning from blue to yellow in an acidic environment and blue to green in a neutral to basic environment. This allows us to visually track any changes in pH during the experiment.
What indicator uses the acronym 'MA'?
The indicator that uses the acronym 'MA' is Moving Average. It is a widely used indicator used to trade trends.
Why is no indicator needed in redox titration experiment?
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.
