Question

What happens when electric current is passed through a voltameter containing acidulated water. On which terminal is hydrogen gas discharged?
Please give answer

Answer 1

Answer:

when electric current is passed through acidulated water the elements present in water that's hydrogen and oxygen gets dissociated into their respective ions that is H^-and O^-2.

Explanation:

I hope I'm right tho

Answer 2

Answer:

When electric current is passed through acidified water, it decomposes to give Hydrogen gas at cathode and oxygen gas at anode

The reaction is given below:

2H20(1)---> 2H2 (g)+O2(g)

At cathode :

when current is passed from battery, the positive ions move towards cathode. They gain electrons and get neutralized to form H2 gas

2H+(aq) +2e---------> H2 (g)

AT Anode:

40H-(aq) 02(g) +2H2O(l) + 4 e
