Question about Base and Acid

[omni]

i need to mark all the Base and Acid in the Equation (in the picture) and tell why i think i choose Them to be acid and base

i mark the Acid in red line and the Base in blue line, tell me if i Right.

my Explanation is HNO is Acid and it give proton While CH3NH2 is base and it gain in the proton but about the other Materials in the Equation i am not sure who is base and who is acid and i need your help here.


thanks.

thanks.

If all the picture is, is 1 equation, can you consider typing it out to help the search function here?

Anyway, on the right hand side of the equation, which species is donating a proton, and which is accepting it?

[omni]

sure i can typing it here but if i will do it is will be really Unclear.

CH3+HNO3<---->NO-3+CH3NH+3


for your answer:NO3 is donating proton and CH3NH is accepting proton yes?

Have a look at the formatting options above where you type, so you can write this out as

CH3NH2 + HNO3 <-> CH3N(+)H3 + NO3-



for your answer:NO3 is donating proton and CH3NH is accepting proton yes?


Not quite, where is the proton for NO3- to donate?

[omni]

ok thanks for let me know about the formatting options.


well tell me if i Right in the way that i mark the Materials on the Left side.


"Not quite, where is the proton for NO3- to donate? "


well so i don't really know. what is the way to know if Material donate or accept proton?

I thought NO3- donate proton Because the (-) i know proton is Positive and if some Material will donate proton he will become more Negative.

thanks

Yes, the red and blue in your image are right. There is no proton (or H+) for NO3- to donate within this structure.

If we write the equilibrium the other way around, as CH3N(+)H3 + NO3- <-> CH3NH2 + HNO3, which species on the left hand side has protons.

Of course this will not always work, but is good enough for this example

[omni]

so in the left side CH3N(+)H3 is the acid and NO3- is the base?

thanks

thanks

Methylammonium is the acid on the left-hand side of the reversed equation, yes.

thank you very much.
