Chemical Questions

[lisa_perry75]

As a student studying Biochemistry I have worked in the lab over the summer and may be able to get access to raw chemicals for my fish tanks such as meth blue etc. This is quite handy and much cheaper... I'm hoping it will be alot more accurate too, such as using the labs pH meter. I do hope this is an appropriate use of this forum section, if not please feel free to move it

Does anyone know how to convert ppm to molar concentration?

For fishless cycling what ammonia should you use (ie ammonium sulphate) and what concentration? (In molar if poss)

What chemicals at what concentration is used for the ammonia test kit?

What chemicals at what concentration is used for the nitrite test kit?

What chemicals at what concentration is used for the nitrate test kit?

What chemicals at what concentration is used for the gH test kit?

What concentration should methylene blue be to make a stock bottle?

What concentration should malachite green be to make a stock bottle?

Does anyone know what the carbon source is in Seachem flourish excel?

Sorry to be so demanding I'm sure I had a couple more, which I'll add in due course.

Well, lisa, I don't know the answers to most of these, and I suspect as a biochem major, you should be able to do a few yourself.

Re: "Does anyone know how to convert ppm to molar concentration?" I bet you do, just know that at these really low concentrations that a ppm is very close to a mg/L. If you don't remember how to go from mass to moles, you need to review your texts.

Same thing with your second question, you want to aim for 4 to 5 ppm. And, with the knowledge of the first question, I bet you can calculate what you need for yourself.

I don't know the answers to the rest, though if you looked in your library for a text on titration, I bet you could find the answers to a lot of those. It would be under the quantitative chemistry section.

Glutaraldehyde.
