during the electrolysis of acidulated water,mass of hydrogen obtained as x times that of O2 and the volume of H2 is y times that if O2.The ratio of y and x
Answers
Answer:
32
Explanation:
The chemical reaction for electrolysis of water is given by:
2 H₂O ⇒ 2 H₂ + O₂
From the chemical equation, we can conclude:
2 moles of Hydrogen and 1 mole of oxygen is produced from 2 moles of water.
Thus mass of hydrogen obtained = mass of 2 moles of hydrogen
= 2 mole x 1 g/mole = 2 g
Mass of oxygen obtained = mass of 1 mole of oxygen
= 32 grams
According to question,
x = mass of hydrogen / mass of oxygen
= 2/32
= 1/16 --------------------------------------- equation (1)
Now, Volume of hydrogen obtained = 22.4 L/mole x 2 moles
= 44.8 L
Volume of oxygen obtained =22.4 L/mole x 1 mole
= 22.4
y = Volume of hydrogen/Volume of oxygen
= 44.8/22.4
= 2
Ratio of y and x = y/x = 2/(1/16) = 32
