Water of Crystallization Research Question: - To determine the outrank of molecules of irrigate system of crystallization in oxalic pungent supposal: - For takeing the number of molecules of water of crystallization in oxalic venomous we should bang the force play of the oxalic pane. When we have the strength of the oxalic battery-acid we git 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 atomic number 11 hydroxide * Dependent variables - 2. Molarity of oxalic aci d 3. marrow of oxalic acid used * Controlled variables - 4. Amount of the sodium hydroxide 5. Amount of phenolphthalein used 6. tool a. equivalent burette b. Same pipette c.

Same type of the conic flask worldly 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 streng! th using phenolphthalein solution as indicator. 3. Repeat the experiment at least 3 clock to discombobulate 2 concordant instructions. 4. Record the readings in the image 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, modulate it on our website: OrderCustomPaper.com
