Rinsed the buret with two 5-mL portions of the NaOH solution. Discard the washings. Observed the markings on the buret. The top is marked 0.0-mL and the bottom 50-mL. Place a small funnel in the top of the buret and slowly pour the NaOH solution into the funnel. NaOH solution reaches the top line‚ lift the funnel and allow the solution to fill top line. Using a small beaker‚ slowly open the stopcock and drain NaOH solution untilthe meniscus of the NaOH solution is at the 0.00-mL line or below

Abstract This experiment is based on copper‚ to synthesize some copper compound using Copper (II) nitrate solution to obtain copper metal at the end. Changes of copper complexes when various are added and filtering out the precipitate by using Buchner funnel for vacuum filtration .The experiment started with preparation of copper (II) hydroxide and addition of copper oxide then addition of droplets of chloride complex. Then the addition of ammonium complex and the preparation of copper metal. And the

to a mixture will pronate the base to a salt and alternately if a base is added the acid will deprotonate to give a salt product. When extraction is performed in a separatory funnel two noticeable layers form and the polar charged aqueous layer can be drained to leave the nonpolar neutral organic layer in a separatory funnel. Salts formed with the addition of acid or case are soluble in

In the fume hood‚ approximately 2g of Ca(OH)2 was dumped from a vail into a 250ml beaker. To avoid any left-over Ca(OH)2 inside the vail‚ certain amount of distill water wad added to it‚ and the vail was shook several times after the lid was closed. Pouring the solution in the vail into the beaker‚ and add distill water until it reached the 100ml line. Then‚ the beaker was put on top of a magnetic stir with a magnetic stir bar placed in it.
