Aim To Find the Number of Moles of Water of Crystallisation in Copper (II) Sulphate salt. Introduction Water of crystallisation is the term given to the molecules of water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most

approximately when the amount of base is slightly higher than the acid. NaOH will be the limiting reagent. Of the two combinations‚ the reaction between NaOH and H2SO4 will likely absorb/release the greatest amount of heat energy‚ because the mole ratio is 2:1‚ whereas the mole ratio of NaOH and HCl is 1:1. Variables The amount of each reagent in acid-base reactions will be systematically varied between the trials‚ and will total 50 mL when combined. One of the two reagents will begin at 45 mL‚ and the

Math Studies: Units Project Talha Mirza 1A Gilmartin Dear noble tribe leaders of T-Island‚ I have created a brand-new system of units for us to use in our daily lives called the T-Dog system. You will find this system to be quite useful‚ as it includes six unique units which measure temperature‚ length‚ time‚ weight/mass‚ volume/displacement‚ and currency. By utilizing these units‚ life will be made easier for us. Moreover‚ if it is ever decided to switch to other well-known systems‚ it is
