Hello!
Answer:
NaOH is Base and H2CO3 (Both 2 and 3 in subscript) is Acid
NaOH + H2CO3 → NaHCO3 + H2O
The compound is basic as in the reaction a strong base NaOH is reacted with a weak acid H2CO3.
pH is more than 7!!!
Hopefully it will help you! ❤️
Explanation:
To form the compound Sodium Hydrogen Carbonate ( NaHCO3), one acid and one base is required to react with each other.
The acid is Carbonic Acid (H2CO3) and the base is Sodium Hydroxide (NaOH)
The reaction supporting the answer is given below:
NaOH + H2CO3 --> NaHCO3 + H2O
The compound formed ( NaHCO3) is weak basic in nature and has pH value slightly above 7.
or
Sodium hydrogen carbonate also known as sodium bicarbonate is produced by chemical reaction between weak acid, carbonic acid and strong base, sodium hydroxide.
Water is formed as a byproduct.
The chemical reaction is as follows.
NaOH + H2CO3 NaHCO3 + H2O.
Commonly known as ” baking soda”, sodium bicarbonate is amphoteric in nature.
Its aqueous solution is alkaline in nature due to the presence of free hydroxide ions (-OH).
