Reactants Lab Essay

aspect 1 Problem What type of chemic substance reactions occurs when different reactants are mixed?Variables Manipulated conclave of reactantsResponding shell of chemic ReactionControlled 1. Same tote up of reactants used (1 human race for solids, 4 drops for lucids)2. blemish plate is washed beforehand reactants are mixed3. Same amount of time substance is anyowed for chemical reaction to occur (15s)4. Because data is qualitative, observations will be made by the analogous person.Aspect 2 Controlling Variables The same amount of reactants macrocosm used will be controlled by using the same amount of reactants in each reaction (1 piece for solids, 4 drops for mobiles).Spot plate will be washed before each chemical reaction (using the piss from the squeeze bottle) to en genuine no residue is go forth from previous reaction. observations will be made 15 seconds after the chemical raction. Time will be unplowed using a watch.The same person will make qualitative observa tions, to ensure that observations are kept consistent.Aspect 3 Materials> Spot Plate> Forceps> Squeeze Bottle change with water> ToothpickList of ReactantsFig. 1.1ReactantChemical Formulaaluminum (s)Al (s) bruiser (II) chloride (aq)CuCl2 (aq)barium hydroxide (aq)Ba(OH)2 (aq)sulphuric venereal infection (aq)H2SO4 (aq) centilitre (aq)Cl2 (aq)sodium banality (aq)NaBr (aq)zinc (s)Zn (s)copper (II) sulphate (aq)CuSO4 (aq)hydrochloric acid (aq)HCl (aq) magnesium hydroxide (aq)Mg(OH)2 (aq)calcium chloride (aq)CaCl2 (aq)sodium carbonate (aq)Na2CO3 (aq)calcium (s)Ca (s)water (l) water (l)sodium acetate (aq)C2H3NaO2 (aq)magnesium (s)Mg (s)sodium hydroxide (aq)NaOH (aq) carbon monoxide chloride (aq)CoCl2 (aq)List of Chemical ReactionsFig. 1.2Reactant 1Reactant 2sulphuric acid (aq)barium hydroxide (aq)hydrochloric acid (aq)magnesium hydroxide (aq)calcium (s)water (l)hydrochloric acid (aq)sodium acetate (aqzinc (s)copper (II) sulphate (aq)cobalt chloride (aq)sodium hydroxide (aq)magne sium (s)hydrochloric acid (aq)sodium bromide (aq)chlorine (aq)aluminum (s)copper (II) chloride (aq)Procedure1.

Referring to Data in Aspect 2 & 3 of Data Collection and Processing, we can see there were 5 single replacement reactions, and 4 double replacement reactions (one of which was a neutralization reaction). The reactions involving an element and a unite were all single replacement reactions, and the reaction involving two compounds were double replacements (which include a neutralization reaction).Aspect 2 Evaluate the Procedure A problem with this procedure is that it doesnt explore all types of chemical reactions. Also, establish as one may, it is sometimes difficult to get the residue of a substance off the spot plate. This tampers with results.Aspect 3 Improving observational Design A few more reactions should be added where simple small-arm and decomposition are shown. Also, using the Bunsen burner, a reaction should be added where hydrocarbon combustion is shown.Disposable spot plates should be used, to ensure that residue left hand by previous reactants and reactions, do not tamper with results.
