Chem Question on DC solutions

[pat w]

Does anyone know or can anyone calculate the weight of 1 liter of a 100 dKH baking soda reference solution? Would it be far enough away from 1 kg to cause a problem when using a .01 g scale to make various ref solutions for drop checkers?

eg .. I weigh out 4.0 g of the 100 dKH and add 96.0 g of distilled water both at room temp. Would I then have a reliable 4.0 dKH solution?

Hi Pat,

If the scale is reasonably accurate (calibrated?), :gw certainly, in fact for our “drop checkers” I think 0.1 gram accuracy is plenty…

Thanks

May try Wet's two DC thingy and this will speed things allong.

Hi Pat,

If you , or perhaps more importantly your significant other, can stand the tank looking like a high school science project for a few days, get 6 (12 for Wet’s marvelous method) or more test tubes and tubing to fit over the test tubes.

Along with your drop checkers, fill the test tubes half way or so as you would your drop checkers, arrange, clip (secure) the test tube and tubing so as to place the open ends of the tubing (cut to length) at various points and depths around the tank.:gw

It is interesting and sometimes eye opening when you see where and how the dissolved CO2 moves and congregates around the tank.
