In lemonade which is present? a)so2 b)co3 c)co2 d)NH3
Hello!!!
Hope you are doing great!!!
The answer is c)CO2
Usually lemonde is a lemon-flavoured corbonated drink.Since lemon is extremely acidic in nature.Its pH is about 2-3.While converting lemon to lemonade Corbondioxide is created.When the acid in the lemon i.e citric acid comes in contact with baking soda then corbondioxide is created.It makes the lemonade fizzy. So corbondioxide is present in lemonade.
Hope it helps!!!
Thank you!!!
