Sodium Bicarbonate Weight to Volume

[Matrix]

Guys,

I am preparing a DIY Co2 drop checker solution for which i need 4dkh reference solution. I don't have a mini measuring scale to measure 1.2g of baking soda (sodium bicarbonate). I have a (2ml) syringe which can be useful if anyone can help me with the calculations.
So the question is how many g = 1ml of baking soda? (weight to volume).

Found this link on net http://www.onlineconversion.com/weight_ ... ooking.htm but still want to double confirm.

Can you rephrase your query with correct units please?
especially the "1ml" of baking soda part, either let us know the PPM/molarity/%by volume.

I am talking about dry powder weight in volume.
For eg:
If I put 1.2g of baking soda powder in a measuring cylinder (in this case 2ml syringe) how many ml will it be?

[saikumar]

2ml, because salt dissolves and volume doesnt change

The link in my first post says 1g =1.071 ml for baking soda (average). Its based on its density so what is the density of our baking soda which we use for cooking

I am not so sure...

I expect soda bicarbonate to be difficult to measure by volume. Grain/crystal size might influence density of granular substances like soda bicarbonate. That itself MIGHT explain why the density you have quoted is an average.

If I were you I would find out the solubility of soda bicarbonate at my ambient temperature and go from there to create a saturated soda bicarbonate stock solution.

It turns out 125 kg of soda bicarb dissolves in 1000 kg of water at 40 deg celcius. http://www.tatachemicals.com/europe/pro ... bility.pdf

So 2 ml will dissolve 0.25 gm of soda bicarb.

Did my method make any sense?

Matrix, please give us your reference link which has concentrations of each.

I think baking soda which we use in cooking all over India has same proportions.

How will you achieve 40dkh solution by this method? (i.e the first stage of DIY drop checker solution ===> mixing 1.2g of baking soda in 1000ml of distilled water will give 40dkh reference solution)

Not clear how this will help me to get 40dkh reference solution. As i said in post above I want to measure 1.2g baking soda but i dont have app scale for it, so trying to measure the same in ml (DRY Baking Soda - No dissolving in water)

I am referring to the densities mentioned in this link http://www.onlineconversion.com/weight_ ... ooking.htm
