Why we used methyl red as indicator in titration borax with HCL?
Methyl red is used as an indicator in the titration of borax with HCl because it changes color in acidic conditions. This allows for the precise determination of the endpoint of the titration, which is when all of the borax has reacted with the acid. The color change indicates the shift from basic to acidic conditions, helping to stop the titration at the correct point.
What can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
What color is methyl orange when hydrochloric acid is added?
The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red.
What is the color of methyl red in boric acid and mannitol?
Methyl red will appear yellow in a boric acid solution and red in a mannitol solution.
What colour will methyl orange turn in vinegar?
Methyl orange will turn red in vinegar due to its acidic pH.

The color change indicates the shift from basic to acidic conditions, helping to stop the titration at the correct point.
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 can be added to HCl to turn red?
Adding phenolphthalein indicator to hydrochloric acid (HCl) will turn it red in basic solutions.
What color is methyl orange when hydrochloric acid is added?
The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red.
Why is methyl red indicator more suitable?
Methyl red is used as a pH indicator or for the identification of some bacteria.
What is the color of methyl red in boric acid and mannitol?
Methyl red will appear yellow in a boric acid solution and red in a mannitol solution.
What colour will methyl orange turn in vinegar?
Methyl orange will turn red in vinegar due to its acidic pH.
What are 3 indcators?
Methyl Orange, Phenolphthalein, Litmus, Red Cabbage, Hydrangeas flower, Methyl red, Naptholpthalein, Bromophenol Blue
What colour is methyl orange in ch3ooh?
The color of methyl orange is red. The color is red when the acetic acid is below pH 3.1.
What is the colour change observed as the end point is approached when borax is titrated against a solution of HCl using screened methyl orange indicator?
When titrating borax with HCl using methyl orange indicator, the color changes from yellow to orange as the end point is approached. This color change is due to the change in pH from basic (yellow) to acidic (orange) as the titration progresses.
What is range of methyl orange?
The pH range of methyl orange is typically between 3.1 (red) and 4.4 (yellow).
Is staphylococcus aureus negative for the methyl red test?
Yes, Staphylococcus aureus is negative for the methyl red test due to its inability to produce stable acids from glucose fermentation. This distinguishes it from other enteric bacteria that are positive for the methyl red test.
