VIII. Table Result Of Experiment
No Procedure Result Hypothesis Conclusion
1. Before :
MnO2(s) : black powder
NaCl (s) : white granule
H2SO4 0.1M:colorless
KI : colorless
Amylum : colorless
After :
-MnO2 (s) +NaCl (s) +
H2SO4 = black color and
theres back precipitate
-After test with wet filter
paper of KI and amylum
the filter paper become
purple
-After heated theres gas of

The faster of filter
paper show the color
is 1b (mixed with
KBr) and 1a is slower
(mixed with NaCl)
Manganese powder (point of spoon)
- Added same grain of NaCl into test tube
- Added a little H2SO4
- Heated
gas
- Hold filter paper wet KI and amylum
solution above gas

1b Before :
MnO2(s) : black powder
KBr (s) : white granule
H2SO4 0.1M:colorless
KI : colorless
Amylum : colorless
After :
-MnO2(s) +KBr(s) + H2SO4
= black color and theres
black pecipitate
-After heated theres gas of
bromin
-After that test with wet
filter paper of KI and
amylum the filter paper
become purplish blue

Bromin gas can make
by reaction between
MnO2(s)+ 2H2SO4(aq)
+ KBr(s)

Caporite : white powder
HCl : colorless
Aquadess : colorless
After
After filtrate the solution
become colorless
After entered a sheet of
colored paper on the two,
the colored paper
become white
2CaOCl2(s) + H2O(l) +
CO2CaCO3 +HOCl
+ CaCl2

The tube without HCl
is more lower to make
a sheet of colored
paper become white
Test tube 2 with HCl
is faster to makeasheet of colored
paper become
white(pale)

chlorin the gas is very
bad smell and colorless
The filter paper become
purple but just a little in
top of filter paper
After solution test with
litmus paper, red litmusstill red and blue litmus
paper become red
KBr formed yellow
color in top of filter
paper and the
bottom is purplish
blue
NaCl formed purple
color but just a littlein top of filter paper
The most
concentrated color
are :
