Here are the solutions to the questions based on the provided graph: 10.1 Step 1: Identify the weakest acid. A weaker acid has a pH value closer to 7. From the graph, we look at items with pH less than 7. Vinegar has a pH of approximately 3. Yoghurt has a pH of approximately 5. Acid rain has a pH of approximately 4. Among these, Yoghurt has the highest pH (5), making it the weakest acid. Step 2: State the pH and name of the item. The pH of the weakest acid is 5, and the item is Yoghurt. pH = 5, Yoghurt 10.2 Acid rain is formed when pollutants like sulfur dioxide (SO_2) and nitrogen oxides (NO_x), primarily from burning fossil fuels, are released into the atmosphere. These gases react with water, oxygen, and other chemicals to form sulfuric acid (H_2SO_4) and nitric acid (HNO_3). These acids then fall to the Earth as rain, snow, fog, or dry particles. 10.3 Step 1: Determine the pH values from the graph. The pH of Vinegar is 3. The pH of Distilled water is 7. Step 2: Calculate the difference in pH. Difference in pH = pH of Distilled water - pH of Vinegar Difference in pH = 7 - 3 Difference in pH = 4 The difference in pH between vinegar and distilled water is 4. 4 What's next? Send 'em! 📸
