tate the colour of methyl orange in alkaline solution

The color of methyl orange at pH = 3a.Colourlessb.Yellowc.Oranged.Red

Methyl orange isDeselect Answer Red in acidic medium, yellow in basic medium Colourless in acidic medium red in basic medium Red in acidic medium, colourless in basic medium Yellow in acidic medium, red in basic medium

When methyl orange is added to hydrochloric acid it turns orange to______

In the titration between a strong acid and a weak base methyl orange may be suitable as an indicator.

A water sample is alkaline to both phenolphthalein as well as methyl orange. 200 mL of a this water sample on titration with N/50 HCl required 9.4 mL of the acid to phenolphthalein end point. When a few drops of methyl orange are added to the same solution and titration is further continued, the yellow color of the solution just turned red after addition of 30.4 mL of the acid solution. Calculate the  alkalinity present in the water sample.a.P = 152 ppm., M =  47ppm and HCO3– alkalinity = 58 ppm, CO32– alkalinity = 94 ppmb.P = 1520 ppm., M =  470ppm and HCO3– alkalinity = 940 ppm, CO32– alkalinity = 580 ppmc.P = 47 ppm., M = 152 ppm and HCO3– alkalinity = 58 ppm, CO32– alkalinity = 94 ppmd.P = 470 ppm., M = 1520 ppm and HCO3– alkalinity = 580 ppm, CO32– alkalinity = 940 ppm
