What is the solution of NaOH in methyl orange indicator?
The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
What indicator would you use if the end point for a titration occurred at pH 10.5?
A suitable indicator for an endpoint at pH 10.5 would be methyl orange. At this pH, methyl orange changes color from red to yellow, making it a good choice for acid-base titrations that end around pH 10.5.
If soda water or any indicator which will change into the colour of red?
Methyl Orange is red in an acidic solution.
How can you determine total acidity?
By titration with alkaline on methyl-red indicator (pH<6)
What would happen if you omitted methyl red in the reaction mixture?
If you omitted methyl red in the reaction mixture, you would not be able to visually monitor or detect the pH change in the reaction. Methyl red is a pH indicator that changes color in response to pH changes, so without it, you would not be able to accurately determine when the reaction has reached a specific pH endpoint.
What indicator would be suitable for a reaction between a strong acid and a weak alkali?
Methyl Red
What colour indicator do you use for hydrochloric acid and vinegar?
Methyl red is an adequate indicator.
What is the solution of NaOH in methyl orange indicator?
The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
What can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
What indicator would you use if the end point for a titration occurred at pH 10.5?
A suitable indicator for an endpoint at pH 10.5 would be methyl orange. At this pH, methyl orange changes color from red to yellow, making it a good choice for acid-base titrations that end around pH 10.5.
Why does adding 6 M HCl to the yellow solution of methyl red tend to cause the color change to red?
Adding 6 M HCl (hydrochloric acid) lowers the solution's pH, causing a shift in methyl red's equilibrium towards the red form. This is because methyl red is a pH indicator that changes color from yellow (at a higher pH) to red (at a lower pH). The addition of acid protonates the indicator, resulting in the color change.
What effect do alkali's have on methyl orange indicator?
Alkalis turn methyl orange indicator yellow because the color of methyl orange changes depending on the pH of the solution. In acidic conditions, methyl orange appears red, while in alkaline conditions it appears yellow.
If soda water or any indicator which will change into the colour of red?
Methyl Orange is red in an acidic solution.
Why methyl orange is used as indicator in determination of ZnO?
Methyl orange is used as an indicator in the determination of ZnO because it changes color from red to yellow at a pH range of 3.1-4.4, which is suitable for the titration of ZnO with a strong acid like hydrochloric acid. This color change helps in determining the endpoint of the titration accurately.
A well known indicator?
Phenolphthalein Litmus Red Litmus Blue Universal Indicator -> Most Common Methyl Orange :)
How can you determine total acidity?
By titration with alkaline on methyl-red indicator (pH<6)
How do you prepare bromocresol green and methly red indicator?
To prepare bromocresol green indicator, dissolve 0.1 g of bromocresol green in 100 mL of ethanol. For methyl red indicator, dissolve 0.1 g of methyl red in 100 mL of ethanol. Store both indicators in a tightly sealed container away from light.
