red in 300 mL of 95% ethyl alcohol. Add sufficient purified
water to make 500 mL.
I found this in the Difco Manual

What is mixed indicator and how it is prepare?
Dissolve 20mg methyl red and 100mg bromocresol green in 100ml 95% ethyl alcohol.
When do you use methyl red instead of phenol red?
You use methyl red as a ph indicator for for the MRVP test.
How do you prepare methyl orange indicator for titration?
5g methyl orange dry dissolved with 100ml distilled water.
What can be added to HCl to turn red?
Methyl Red Indicator
How to make Methyl Orange Indicator from the powder?
Methyl Orange indicator is made by dissolving .01 g of the powder into 100 ml of DI water. This gives and indicator for a pH range of 3.2-4.4 and goes from Red to Yellow.
Why is methyl red indicator more suitable?
Methyl red is used as a pH indicator or for the identification of some bacteria.

A well known indicator?
Phenolphthalein Litmus Red Litmus Blue Universal Indicator -> Most Common Methyl Orange :)
How to make Methyl Orange Indicator from the powder?
Methyl Orange indicator is made by dissolving .01 g of the powder into 100 ml of DI water. This gives and indicator for a pH range of 3.2-4.4 and goes from Red to Yellow.
How can you determine total acidity?
By titration with alkaline on methyl-red indicator (pH<6)
What effect do alkali's have on methyl orange indicator?
It turns the alkali into a red/yellow colour
