1.	State your observation when dilute hydrochloric acid is added to sodium carbonate crystals
Answer» Metal CARBONATES are basic SUBSTANCES. So, their reaction with strong mineral acids like hydrochloric ACID is often termed as neutralisation reaction. Both metal carbonates and bicarbonates get readily decomposed by mineral acids with evolution of carbon dioxide (CO2) bubbles. When hydrochloric acid is added to SODIUM carbonate, brisk effervescence of CO2 occurs, along with the FORMATION of sodium chloride and water. Na2CO3 + 2HCl = 2NaCl + CO2 + H2O
