I’ve been using a mostly food based version for a few months now. So far so good.
I have a few ingredients (table salt and choline bitartate) that I add in chemical form in relatively small quantities. I have some scales that apparently are accurate to 0.1g but I don’t really trust them. I’m thinking about pre-disolving 100g of salt (say) in 1L of water and simply pipetting the required amount as i make each meal. A quick time in motion study of me pipetting vs measuring the weight of each would save ~1 minute per meal (which is about 25% of total time spent preparing, consuming and cleaning up after myself). My questions are:
- Are there any issues with storing chemicals dissolved in water in
the long term (e.g. >2 months)? It will be in an airtight, dark
bottle. I cannot imagine any issues with the salt solution, but am
not sure about the choline bitartate.
- Are there any chemists who could tell me if both chemicals would react with each other if I stored them both in the same solution? (i.e. so I only have one liquid to pipette rather than two). When i mix the two together i cannot see anything happening (no effervescence, etc) but that doesn’t mean there is no reaction.
- I anticipate the error in the measurement using pipettes will be smaller than i currently have weighing the ingredients (see here for an explanation). Is anyone aware of any potential risks with accuracy using this approach?
