Electrolysis of Water

I have used a battery and water treated with washing soda to separate water into hydrogen and oxygen in class. Can someone explain in simple terms what happens to change the water into two gases?? I understand that why there is twice the hydrogen as oxygen, but the Chemistry gobbledygook has me confused.
