With the recycling aluminum—synthesis of alum chemistry laboratory kit, students perform a multi-step chemical reaction with aluminum foil students use dissolution, crystallization and filtering techniques to produce solid alum. This is my work on lab report on synthesis of alum i got 41/44 from this lab report i hope it might be helpful to you. The term alum is a general family name for a crystalline substance composed of cations with 1+ and 3+ charges in this experiment, you will synthesize a type of alum called potassium aluminum sulfate dodecahydrate, kal(so4)2•12h2o you will synthesize this compound by placing the appropriate ions in one container in. Safety: potassium hydroxide and sulfuric acid solutions are caustic and/or corrosive avoid contact with skin, eyes, and clothing one reaction produces hydrogen gas (h2) which can be explosive this reaction should be performed in a well- ventilated area or fume hood eye goggles and appropriate lab attire should be. We call a hydroxide that can react with either acids or bases amphoteric ( synthesis of alum from aluminium, 2001) 2 a1(s) + 6 h2o (l) + 2 koh (aq) 2 k [al (oh)4] and produce a better yield of the end product conclusion the aim of the experiment was definitely fulfilled that alum was synthesised from scrap aluminium. This is a video i made during my last lab might get used in a lab report, not sure the editing in this video is very basic i just switched from sony movie.
This experiment was designed to recycle aluminium into alum crystals which have uses in industry the aluminium was converted to alum by heating these particular research questions will be answered throughout this eei: how the mass of the scrap aluminium related to the final mass of the alum. School of engineering and science 306853 chemistry 064 semester ii, year 2015 laboratory report synthesis of alum from soda can erik ngoi yiew tuang/2e3/ radiant 17/9/2015 fp-028 chemistry 064 experiment no2 abstract this experiment was conducted to synthesize alum from aluminium cans. Experiment 4: synthesis of alum from scrap aluminum objective: in this experiment, you will be converting the aluminum metal from a beverage can into the chemical compound potassium aluminum what conclusion can you draw from the test with bacl2 2 what did you see in the flame test, and does this confirm the.
Synthesis and analysis of alumthis experiment will introduce you to several fascinating aspects of the chemistry of aluminum and it. Experiment 3 synthesis of alum 3-1 name___________________________________________________________lab day__________lab time_________ experiment 3 synthesis of alum pre-‐ lab questions answer these questions and hand them to the tf before beginning work (1) what is the purpose of this.
Synthesis of alum, kal(so4)212h2o objectives dissolving aluminum foil gravity filtration reactions that complete alum formation crystallization vacuum filtration work in pairs can be completed don't forget to bring the lab handouts back to the next lab period, because the lab report is due in the next lab period. Synthesis of alum: kal(so4)2•12 h2o hazard warning: the sodium hydroxide used in this experiment is highly corrosive if you get it on your skin, wash immediately if your skin feels slippery, that is a sign that you have gotten the sodium hydroxide on you introduction the purpose of this experiment is to use aluminum.
