The wiki hasn't been updated... The best thing for you to do is look at the Training Handout and PowerPoint, which can be found at soinc.org. There are a lot of useful notes there.My coach told me this morning that I will be competing Water Quality for the first time on Saturday. My partner has done it before, but she didn't have any notes. Please help!!! Has the Wiki been updated yet???
wait, back in the first year of WQ there was a rules clarification on how to make the saline solution for salinometer testing.I noticed that I was making a mistake calibrating my salinometer, and I'm thinking this might be a common mistake. When mixing saline solutions I would mess up my total. For example, if I wanted 4% salinity, I would mix 400 g of distilled water with 16 g of salt, because 16 is 4% of 400. However, my total solute to solution ratio would be 16 g of salt over 416 total grams of saltwater solution, and 16 is not 4% of 416. Basically, my results were thrown off because I didn't take into account the total amount of solution. What I should have done to get 400 g of 4% salt water was to mix 16 grams of salt with 384 grams of water. Has anyone else made this mistake?
