0,5 dikali 3per5 - 4% = Harus dengan jalannya

Jawaban:

Penyelesaian :

0,5 [tex]\sf × \: \frac{3}{5} \: -[/tex] 4%

[tex]\sf = \frac{5}{10} \times \frac{3}{5} - \frac{4}{100} [/tex]

[tex]\sf = ( \frac{5}{10} \times \frac{3}{5} ) - \frac{4}{100} [/tex]

[tex]\sf = \frac{15}{50} - \frac{4}{100} [/tex]

[tex]\sf = \frac{30 \: - \: 4}{100} [/tex]

[tex]\sf = \frac{26}{100} [/tex]

[tex]\sf = \frac{13}{50} [/tex]

b A white crystalline salt of sodium produces a gas when dilute hydrochloric acid is added to it. What two tests can you do to show whether the substance is sodium carbonate, sodium sulfite or neither? State the tests and give the observation expected with a positive test.

Jawaban:

1. Ca(OH)2 solution test and

2. K2Cr2O7 solution test

Penjelasan:

'Kay, so the goal is to differentiate chemical test of gases, whether it comes from Na2CO3, sodium bicarbonate, or Na2SO3, sodium sulfite.

The gas sample can be delivered using small pipe into 2 solutions: one is solution of Ca(OH)2, calcium hydroxide, and another one is solution of K2Cr2O7, potassium dichromate(VI).

Ca(OH)2 (aq) --> to test presence of CO2 gas and SO2 gas

(+) test = formation of white precipitate

(-) test = no precipitate formed

K2Cr2O7 (aq) --> to test presence of SO2 gas only

(+) test = color changes from orange to green

(-) test = no color change observed

If the gas produced from the reaction is CO2, it will give positive test to Ca(OH)2 test, but negative test to K2Cr2O7 test

If the gas produced from the reaction is SO2, it will give positive test, both to Ca(OH)2 and K2Cr2O7.
