Magnesium metal and hydrochloric acid solution The ribbon and lab materials, the solution. C3 Chemical reactions. The correct observations are: (c) Granules has increased surface area for fast reaction. Not all metals react this way, but many do. > If an acid releases one H+ ion, it is called monobasic acid, e.g., HCl, HNO3, CH3COOH. > If an acid releases two H+ ions, it is called dibasic acid, e.g., H2SO4, H2CO3. Sodium carbonate reacts with acids to give (c) NaOH 6. But unlike the reaction between acids and bases, we do not get water. Carbon dioxide gas is collected by the upward displacement of air because: > When bases react with metals they do not release hydrogen gas. Chemists use strong acids and bases to get chemical reactions in the lab. Development: i. (b) chlorine > Carbon dioxide gas test: To test the carbon dioxide gas, allow the gas to pass through freshly prepared lime water. Acids and bases are found all around us: In the food we eat, the beverages we drink, many of the everyday household products at home and even inside us! 35. > Acids: Acids are defined as proton donors because they lose H+ ions. (c) Sodium hydroxide (a) the surface of the metal turns shining (b) Hydrogen is neutral. Neutral solutions (like distilled water) with a balanced number of H+ and OH- ions have a pH of 7. When dilute HCl is added to granulated zinc placed in a test tube, the observation made is: The metals which react with acid and alkalies to produce hydrogen gas are Question 4: Activity 2.5 NCERT Class 10 Science, Chapter 2 Acids, Bases, and Salts.
