Experiment 2: Chemical Reactions
Date: 02/10/2020
Title: Chemical Reactions
Purpose: To observe the various types of chemical reactions and their results.
Procedure:
Examples will be conducted of the different types of chemical reactions
6 types of Simple Chemical Reactions
Reversible Reactions
Data, Calculations, Conclusions:
Examples of 6 Types of Reactions:
Double Displacement Reaction of two solutions: HCl (aq) and AgNO3 (aq)
Reaction: white solid formed in tube = silver chloride (AgCl)
two solution that were clear and colorless formed solid
Ag+NO3- (silver nitrate solution) + H+Cl- (hydrochloric acid solution) ---> H+NO3- (nitric
acid solution) + AgCl (silver chloride; precipitate)
Double displacement reaction: a reaction in which the positive (+) and negative (-) ions
of two reactants are interchanged
Double Displacement Reaction #2: Kl and Pb(NO3)2
Two colorless solutions forms yellow solid of lead iodine (Pbl2) at the bottom of test
tube
solid yellow was used for pigment in yellow paints led to lead poisoning in babies
Pb+2 (NO3-)2(lead nitrate solution) + 2K+I- (potassium iodine solution) ---> K+NO-3
(potassium nitrate solution; colorless solution) + Pbl2. (lead iodine; yellow precipitate)
Double Displacement Reaction #3 (Acid-Base): NaOH & HCl
Acid-Base Reaction: a reaction in which the positive and negative ions of acid and base
reactants are interchanged with the evolution of heat and usually the formation of water
Exothermic (heat given off)
Acid- a reactant containing H+ ion which can be donated
Base- a reactant whose anion (-ion) can accept H+ ion
NaOH and HCl: Starting temperature of 21.5C for both
After the two solutions combined, no solid or gases formed;
Temperature is 30.5C and rising; over 10 degree rise
H+Cl- (hydrogen chloride solution) + Na+OH- (sodium hydroxide solution) ---> Na+Cl-
(sodium chloride solution) + H2O (water) + heat
Double Displacement Reaction #4 (Acid-Base): HCl & NaHCO3
