Question
A student was titrating the calcium and water solution and notice the formation of bubbles in the flask. Which description would best describe what is occuring?
sodium hydroxide was added to the buret when titrating the solution. This resulted in sodium hydroxide reacting with water forming H2(g).
not all the calcium turnings reacted with water in the first step. Therefore, when acid is added to the solution it reacts with calcium to form O2(g).
this normally occurs when titrating.
too much HCl was added causing which reacted with water forming H2(g)
