The experiment was about creating solutions of standard molarity and measuring concentrations. No. Question: Name Formula of Hydrates Lab Report Data and Calculations: Copper (II) sulfate hydrate Trial 1 Trial 2 19.244 20.546 24.504 27.689 Mass of crucible and cover (6) Mass of crucible, cover, sample before heating is) Mass crucible, cover, sample after heating (8) Mass of hydrate() 22.606 25.111 Mass of anhydrous solide Mass of water driven off (e) Moles of water X is a specific whole number value. The equation for the decomposition of copper (II) sulfate is CuSO4 (aq) ==> SO2(g) + CuO(s). So the practical involved taking hydrated copper sulphate, heating it to drive off the water, weighing before and after, and thus calculating the number of water molecules of crystallisation, based on the respective molecular weights of the anhydrous salt and water. copper (II) sulfate hydrate. Send me a message, I'd love to hear from you! Does a password policy with a restriction of repeated characters increase security? Copper Sulfate absorbs water easily, forming a weak bond between the copper sulfate and five water molecules. You might also like these related lessons! The mass was reduced to 7.58 g. What is the formula of the hydrate? Safety: Patel A student trying to determine if a white solid is a true hydrate heats the sample and finds that there is evolution of water, that the residue obtained is soluble in water and that the solution is colorless. The electronic scales (quite cheap) were an obvious first candidate for a source of error. What can this chemical be? Copper sulphate ; CuSO4.5H2O (NB The 5H2O is the water of hydration held in the crystal ; like you hold a tennis ball in your hand). * Cup Each worksheet has a full preview available. I was born December18,1963When would I graduate high school? In this section we will demonstrate the dehydration and re-hydration of cobalt (II) chloride hexahydrate. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. In this section we will determine the number of moles of water present per mole of anhydrous solid in a given hydrate. This lab explored hydrates and the 4 objectives in a three procedure process through observation, experimentation, and mathematical methods to help prove whether dehydration of a hydrate is, Equipment and materials used in one or more procedure included: Hydrated copper sulfate, observation and experimentation. \[ \underbrace{\ce{CuSO4*5H2O (s)}}_{\text{Deep Blue}} \ce{->[\Delta]} \underbrace{ \ce{CuSO4 (s)}}_{\text{Ashy White}} \ce{+ 5 H2O (g)} \label{1}\], \[ \underbrace{\ce{CuSO4 (s)}}_{\text{Ashy White}} \ce{->[\ce{H2O (l)} ]} \underbrace{ \ce{CuSO4 (aq)}}_{\text{Deep Blue}} \label{2}\]. Interpreting non-statistically significant results: Do we have "no evidence" or "insufficient evidence" to reject the null?
