Introduction: The copper (II) sulphate is then placed in 100 mL of distilled water. Then 20 mL of CuSO4 is measured and placed 100 mL of distilled water. This can later be weighed to determine the mol of CuSO4 and the mol/L concentration. Then this was used to find out how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II) sulphate in solution. Then titrate ¼ of the estimated amount number of mL of NaOH needed to react with the sulphate solution. Then add 5 mL at a

Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction‚ an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus‚ the enthalpy change for the reaction can be measured. The equation of the above

SynopsisThe objective is to determine the amount of Sulphate in anhydrous Barium Sulphate precipitate by gravimetric method. Gravimetric method is by the quantitative determination of the mass of anhydrous Barium Sulphate precipitate. Barium sulphate precipitate is form when Barium Chloride is added excessively to a hot given Sulphate solution slightly acidified with concentrated Hydrochloride acid. The white precipitate of hydrate Barium Sulphate formed is than digest‚ filtered out‚ washed and dried

When magnesium was placed separately in the copper sulphate solution and zinc sulphate solution‚ it was able to displace both the copper and zinc (in the copper sulphate solution and
