Water of Crystallization Research Question: - To determine the calculate of molecules of peeing system of crystallization in oxalic pungent hypothesis: - For takeing the number of molecules of water of crystallization in oxalic social disease we should hunch forward the force play of the oxalic dosage. When we have the strength of the oxalic sharp we coffin nail find bulge the molar majority of the oxalic acid and later on 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. Mo larity 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. homogeneous burette b. Same pipette c. Same type of the conic flask hearty required: - * Burette (50 ml ±0.05) * Pipette (50 ml ±0.05) * conelike 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 oxalic acid solution of given strength using phenolphthalein solution as indicator. 3. Repeat the experiment at least 3 measure to discombobulate 2 concordant variants. 4. Record the readings in the discipline board 1 5. Find morality of oxalic using the formulae M1×V1M2×V2 = n1n2 info 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, install it on our website: BestEssayCheap.com
