प्रश्न
Answer the following question.
Identify the acid and base which form sodium hydrogen carbonate. Write the chemical equation in support of your answer. State whether this compound is acidic, basic, or neutral. Also, write its pH value.
उत्तर
Sodium hydroxide(base) and hydrogen carbonate(acid) combine to form sodium hydrogen carbonate.
\[\ce{2NaOH + H2CO3 -> Na2CO3 + 2H2O}\]
Sodium hydrogen carbonate is a basic salt because NaOH is a strong base and H2CO3 is a weak acid.
pH value of sodium hydrogen carbonate is 8.27.

Which of the following is used for dissolution of gold?
In the following schematic diagram for the preparation of hydrogen gas as shown in the figure, what would happen if following changes are made?
- In place of zinc granules, same amount of zinc dust is taken in the test tube
- Instead of dilute sulphuric acid, dilute hydrochloric acid is taken
- In place of zinc, copper turnings are taken
- Sodium hydroxide is taken in place of dilute sulphuric acid and the tube is heated.
Take a clean test tube with a holder and pour some dilute hydrochloric acid. Add a few pieces of magnesium ribbon pieces slowly. What do you observe? Now show a burning match stick near the mouth of the test tube. Do you hear any sound? The gas burns with a pop sound. From this, it is observed that hydrogen gas has been formed due to the reaction between acid and metal.
