Names for things
Jan. 17th, 2019 12:14 pmI've been reading through science protocols for my class and I keep reading about Domestos. When I first read this I freaked out not knowing what the heck that was and worrying that I would not be able to find that reagent and complete the protocol. (You all in the know are probably laughing at me right now.)
Yahoo for helpful google telling me it's bleach. Bleach. And a bleach brand from the UK. Lo and behold that book and subsequent manuscript was published from UK labs.
So grrr the researchers who used brand names and not just calling it bleach with the name brand in parenthesis like you should. Yes, the concentration of sodium hypochlorite (active ingredient in bleach) is different. Domestos has 5.25% and Chlorox (US brand) has 6.05%. Which can matter when making solutions..... Or not much. But if I were to be a good scientist, I would convert the percentages of one to the other to make sure the solutions were exact. Or not because it's bleach and I'm not sure 22% and 20% are that different in their bacteria killing powers.
Also ran into another difference. What is the difference between an UK and US apple pie? Google did not provide a good answer for this. Apple pie that I make has flour, vegetable shortening, salt, water and cinnamon in the crust. The filling has apples (Macintosh or Cortlands), cinnamon, tapioca pearls (thickener), sugar, and butter.
