LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt‚ x. The salt is crystalline‚ deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt x with NaOH‚ or NH4OH the cation could be distinguished by observing the color changes or solubility while reacting salt x with H2SO4 or a mixture of copper

(Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain base elements of carbon‚ oxygen and hydrogen. (Lea‚ 2002) The simplest carbohydrate molecule

The aim of this experiment was to calculate the concentration of an unknown solution of Sodium Hydroxide (NaOH) by titrating it with Hydrochloric Acid (HCl) and to identify any possible sources of error. A colour change from pink to yellow signified the end of each individual titre as the NaOH had been neutralised. Experimental: Method: Firstly two solutions were prepared to show the colour of the Phenol Red indicator in acid and alkaline conditions. These colours were then used to determine the
