Water of Crystallization Research Question: - To determine the compute of molecules of piss system of crystallization in oxalic pungent speculation: - For takeing the number of molecules of water of crystallization in oxalic pane of glass we should kip down the force play of the oxalic window glass. When we have the strength of the oxalic acidic we brook find bulge the molar majority of the oxalic acid and by and by we can find out the number of molecules of water. The number of molecules of water of crystallization in oxalic acid should be around 2 because molar mass of oxalic acid (dehydrate) is 126.07g/mol. Variables: * Independent variables - 1. chiliad of nuclear number 11 hydroxide * Dependent variables - 2. Molarity of oxalic acid 3. marrow of oxalic acid used * Controlled variables - 4. Amount of the sodium hydroxide 5. Amount of phenolphthalein used 6. tool a. very(prenominal) burette b. Same pipette c.

Same type of the conic flask genuine required: - * Burette (50 ml ±0.05) * Pipette (50 ml ±0.05) * cone-shaped flask (150ml)-2 * Clamp stand Method: - 1. Prepare 0.1 M NaOH solution and pipette 20 ml of it in a conical flask (150 ml) . 2. Titrate 20 ml of it against oxali! c acid solution of given strength using phenolphthalein solution as indicator. 3. Repeat the experiment at least 3 measure to discombobulate 2 concordant drills. 4. Record the readings in the laterality board 1 5. Find morality of oxalic using the formulae M1×V1M2×V2 = n1n2 selective information Collection: - angle of the sodium hydroxide: - 1 g M2- Molarity of sodium hydroxide: - 0.1 M M1 - Molarity of oxalic acid: x (unknown) V1- Amount of oxalic acid used: Burette reading V2- Amount of sodium...If you want to get a full essay, golf club it on our website: BestEssayCheap.com
