known‚ of a strong base. The titrant reacts with and consumes the acid via a neutralization reaction. The point at which stoichiometric amounts of the acid and base have combined is the equivalence point. An example of this is shown in the equation: HCl(aq)+NaOH(aq)NaCl(aq)+H2O(l). The number of moles is given by knowing the exact concentration and volume added of the titrant. The latter‚ in turn‚ is related by stoichiometry to the number of moles of acid initially present in the unknown. To detect

report my findings. Between the topic of the experiment‚ teacher‚ and students the demonstration proceeded without a hitch. The type of experiment I was performing made me very anxious. Questions like‚ “Will the glue and borax solution bond properly‚ did the lab give me enough borax to dissolve in the water‚ and will the students understand what in the heck I’m talking about?” ran through my mind a time or two. In preparation‚ I learned a lot more than I thought I would because I had to have an understanding

In this experiment we investigate the properties of SLIME. Substitution of polyvinyl alcohol instead of Guar gum makes this experiment quite accessible. The Slime is prepared by mixing a solution of (Na2B4O7*10H2O) sodium tetraborate decahydrate (Borax) and H2O with a solution of polyvinyl alcohol (pva) and H2O. Then stirring for ~10 minutes to obtain the final product‚ SLIME. The product was examined and noted on the “non-Newtonian fluid” properties. Object The object of this lab is to become

It has the electron configuration of 1s22s22p1 and is in group 3 or goup 13 (IUPAC classification). In nature‚ it consists of two isotopes 10B (19.6%) and 11B (80.4%). Boron is bonded to the oxygen in nature. The important sources of Boron are borax and kernite. Boron oxides
