Please help me make analysis scheme flow chart for the detection of cation present in my unknown salt mixture of Ag+, Pb2+, or C
1 answer:
The possible action your solution might contain is amongst ,
, or
.
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.
NaCl: 20 drops of NaCl were used and no precipitate was formed.
No precipitation formed means the cation is soluble in water. From your chart, you might see the halide of
and
is insoluble in water, which means they should have formed precipitation but you didn't. This means there's less possibility it contains
or
, so we are left with only
. Let's confirm it with the rest.
: 20 drops of
were used yellow precipitate was produced.
Even though all other sulfates form precipitation ( Insoluble in water)
: 20 drops of sodium carbonate were used and the silver-blue precipitate was produced.
It seems all of their Carbonate is insoluble in nature. ( which is our case too ).
From the above result, only the reaction with NaCl was deemed to be decisive and it indeed contains ions. Means you are correct.

Answer: Oxygen
Explanation:
As seen from the balanced equation:
2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.
According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.
Thus if x moles of both gases are present, x moles of hydrogen will combine with moles of oxygen and
moles of oxygen will be left used and will be in excess.
