Ma'am....I want to ask question...ma'am I m performing titration of water sample from paddy fields...I have added phenolphthalein indicator ..pink colour appears and then titrate against H2SO4 ...when pink colour disappears I have noted down reading ...after that I have added methyl orange but methyl orange immediately show orange colour not showing yellow colour and also does not change to any colour when titrate against H2SO4 ....ma'am this point has confused me why it is happened? ....ma'am please give me your appropriate answer

[@dr.poonamverma-chemistry9065]

That means P=M And your sample has only OH ions.

[@LIPSASAHU111]

Madam agar water me oh ion nhi hoga toh pink colour nhi hoga toh kuch problem hoga kya

[@dr.poonamverma-chemistry9065]

Pink colour appears in basic medium, if OH is not present then it's appears in presence of corbonate also. If pink colour did not appeared then alkalinity may be due to presence bicarbonate ions only

[@ashutoshsrivastava9496]

Thanku mam today is my practical...

[@swetagayen7593]

Ma'am, what is the pH of That methyl orange indicator u were using? I used methyl orange indicator with pH 2.9-4.6 but the colour didn't change to any colour during the 2nd time titration.

[@dr.poonamverma-chemistry9065]

4.3 - 8.3

mam why dont we use only methyl orange to determine the alkalanity

[@dr.poonamverma-chemistry9065]

If you u want to determine only total alkalinity of water then you can use only methyl Orange but if you want to determine types of alkalinity then you have to use both indicator. Ist phenolphthalein then 2nd methyl Orange.
