No, they are absolutely not the same thing. They are completely different compounds: baking soda is sodium bicarbonate (nahco3), and citric acid is c6H8O7c. And they are not even chemically similar. Baking soda is a base and citric acid is (surprise) an acid.
Can you mix citric acid and baking soda?
When citric acid and baking soda react with each other, they chemically change to form sodium ions, citrate ions, carbon dioxide gas, and water. Carbon dioxide gas is a normal component of our air. It is also the gas that makes up the bubbles in carbonated beverages and is naturally exhaled.
Why is citric acid so expensive?
Professor Antonio Saravia of Mercer Economics says that one of the reasons groceries are becoming more expensive is the price of citric acid.

Does boiling affect pH?
When water boils, both hydrogen and hydroxide ion concentrations increase to the same degree. Thus, it is neutral. As the hydrogen ion concentration increases, the pH decreases from 7 to 6.4. Also, as the degree of water dissociation increases with increasing temperature, the value of KW also increases.
