The two ions to be distinguished are : Chloride ion and sulphate ion
The chloride ion can be identified by addition of silver nitrate to the solution containing chloride ion
On addition of silver nitrate, chloride ion will react with silver ions to form a white precipitate of silver chloride
The reaction is
Ag+ (a) + Cl-(aq) ---> AgCl(s)
the solution containing sulphate ion can be identified by adding barium chloride
Ba+2 + SO4^-2 ----> BaSO4(s), white ppt
thus barium chloride reacts with sulphate ion to form white ppt

Determine the total distance
This is calculated by summing up the distance in each segment.


Answer:
P(total) = 15 atm
Explanation:
Given data:
Pressure of O₂ = 5.75 atm
Pressure of N₂ = 7 atm
Pressure of He = 2.25 atm
Total pressure inside tank = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 5.75 atm + 7 atm + 2.25 atm
P(total) = 15 atm
