Hey all!

This is my first post here!

I'm trying to lean back into chemistry, but I need some help and explanation that
I hope you can help me with.

I'm to calculate pH in wine that contains 1.72 g monosodium tartrat(E335) per liter.
(pH is only calculated from that salt in the solution)

The molar mass of monosodium tartrat is 172,07 g/mol

I would be very happy if someone could tell me hwo to approach and solve this
problem.

Thanks,

Nicholas

First step - mass and volume to molarity.

Well, should I take the 1.72 g and divide by the molar mass:

1.72 g / (172.07 g/mol)  =  0.009996 mol ?

...And then divide the moles with the volume(1 L)? This will give M = 0.009996

Thanks! Standing by for advice:)

Instead of standing by you should be working on calculation pH of the tartrate. Have you checked what it is? Ka values? We can help, but don't expect spoon feeding.

[AE35]

Do you think you might put a little too much into the 'standing-by' statement?

You really think that I gave the impression that I wanted to be spoon fed? After two
whole posts?

Bye
