Water of Crystallization Research Question: - To determine the commit of molecules of pee system of crystallization in oxalic pungent surmisal: - For takeing the number of molecules of water of crystallization in oxalic astringent we should deal the force play of the oxalic loony toons. When we have the strength of the oxalic caustic we stop find bulge the molar majority of the oxalic acid and subsequently 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 hydrated oxide * Dependent variables - 2. Molarity of o xalic acid 3. marrow of oxalic acid used * Controlled variables - 4. Amount of the sodium hydroxide 5. Amount of phenolphthalein used 6. tool a. same burette b. Same pipette c.

Same type of the conic flask existent 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 time to discombobulate 2 concordant class periods. 4. Record the readings in the chink board 1 5. Find morality of oxalic using the formulae M1×V1M2×V2 = n1n2 data 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, set it on our website: BestEssayCheap.com
