Chapter 6: Problem 9

Fill in the blanks. The salt obtained by partial neutralization of sodium hydroxide and sulphuric acid is____ in nature.

Short Answer

Expert verified
Answer: The salt obtained from the partial neutralization of sodium hydroxide and sulphuric acid is acidic in nature.

Step by step solution

01

Determine the chemical reaction of the partial neutralization.

When sodium hydroxide (NaOH) partially neutralizes sulphuric acid (H2SO4), it will produce sodium hydrogen sulfate (NaHSO4) as a salt. The balanced chemical equation for this reaction is: NaOH + H2SO4 → NaHSO4 + H2O
02

Determine the nature of NaHSO4.

Sodium hydrogen sulfate (NaHSO4) has both acidic hydrogen ions (H+) from the acid (H2SO4) and a basic hydroxide ions (OH-) from the base (NaOH). However, the balance is not equal, as there is still one acidic hydrogen ion (H+) left in the NaHSO4 molecule. This makes the salt acidic in nature. So, the salt obtained by partial neutralization of sodium hydroxide and sulphuric acid is acidic in nature.
