WebStage 1. Using a small funnel, pour a few cubic centimetres of 0.4 M hydrochloric acid into the burette, with the tap open and a beaker under the open tap. Once the tip of the burette is full of solution, close the tap and add more solution up to the zero mark. (Do not reuse the acid in the beaker – this should be rinsed down the sink.) http://api.3m.com/na2co3+hcl+titration
WebQuestion 6 2 pts Using dimensional analysis, what is the volume that would be required to reach the second endpoint for a HCl and sodium carbonate titration that has a known HCl concentration of 0.1700 M and a known mass of 0.1854 g of sodium carbonate?
