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

chlorin

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)

Manganese powder (point of spoon)

- Added same grain of KBr into test tube

- Added a little H2SO4

- Heated

gas

3 Before

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

HOCl + H++ Cl-Cl

+ H2O

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)

4a Before

NaCl = colorless

H2SO4= colorless

KI : colorless

Amylum : colorless

After

After flowet to water

dilluted theres gas of

NaCl(s)+H2SO4(aq)NaH

SO4(aq) + HCl (g)

a.

Theres gas of

chlorin

b. Theres gas of

bromin

c.

Theres gas of iodin

KI formed much

purplish black color

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 :

KI > KBr > NaCl
