• Each student will receive approximately 100 mL of an unknown HCl. The approximate concentration of HCl will be 0.1 M or 1.0 M. There will be a common container with NaOH. The approximate concentration of NaOH will be 0.1 M or 1.0 M. You will be given the approximate concentrations of NaOH and HCl on...

To measure the amount of nickel in some industrial waste fluid, an analytical chemist adds 0.460 M sodium hydroxide (NaOH) solution to a 23.0 g sample of the fluid and collects the solid nickel II) hydroxide (Ni(OH)2) product. When no more Ni (OH) is produced, he filters, washes and weighs it, and finds that 206. mg has been produced The balanced chemical equation for the reaction is: Ni2+(aq) + 2NaOH(aq) Ni (OH)2(s) + 2Na+ (aq) ■ precipitation x 10 acid-base...

EXPERIMENT 9 SYNTHESIS OF 2-BUTOXYNAPHTHALENE OH 1. NaOH, ETOH .LT 2. n-BuBr DISCUSSION: Nucleophilic substitution reaction is a frequently used method to convert one functional group into another. A nucleophile is mixed with an electrophile and the nucleophile replaces the leaving group to produce a new compound. In this experiment, a weak nucleophile (2-naphthol)...
