I racked and measured four batches<\/a> the other day, and it gave me the opportunity to size up my new buffer solution<\/a>. I recorded TA values for three of those batches while I was still using my old buffer solution to calibrate my pH meter, and they shouldn’t have changed much. Here are the data:<\/p>\n

Since I’m measuring my liquid volumes with the plastic syringe that came with my cheap acid test kit, not pipettes or burettes, I don’t think I can claim accuracy better than 1 g\/L. So I’m not going to say the new buffer is great, but any error its causing is pretty small.<\/p>\n","protected":false},"excerpt":{"rendered":" I racked and measured four batches the other day, and it gave me the opportunity to size up my new buffer solution.
