Snape and Dumbledore both agree that safety must be a priority. Before we get into the more challenging questions they think we should review some safety practices. For the reactivity of metals experiment which of the following is a laboratory safety precaution? Please read all the choices before choosing an answer. A) Since you will be working with hydrochloric acid (6M) care must be exercised not to get this acid on your clothes or skin. If you should come into physical contact with it, wash if off as fast as possible with copious amounts of water. Then inform your teaching assistant of your spill. B) You must wear goggles in this laboratory. C) Handle your thermometer with care. When you remove it from your drawer be sure to hold both ends of the thermometer so that it does not slip out. D) No flames of any type will be permitted in the laboratory while this experiment is being performed.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. ï‚· fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) ï‚· record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. ï‚· record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
