A student checked the pH of various food ingredients and marked them on a pH chart, as shown.Which statement is true?A Milk is more acidic than lemon juice and apple juice.B Baking soda is more acidic than milk and maple syrup.C Apple juice is more acidic than lemon juice but less acidic than milk.D Maple syrup is more acidic than milk but less acidic than apple juice.

Based on the given pH chart, we can analyze the acidity levels of the different food ingredients. Let's go through each statement and determine if it is true or false.

Statement A: "Milk is more acidic than lemon juice and apple juice." Looking at the pH chart, we can see that the pH value for milk is 6.5, while the pH values for lemon juice and apple juice are both below 6.5. Therefore, statement A is false.

Statement B: "Baking soda is more acidic than milk and maple syrup." Baking soda is actually a base, not an acid. So, it is not appropriate to compare its acidity level with milk and maple syrup. Therefore, statement B is false.

Statement C: "Apple juice is more acidic than lemon juice but less acidic than milk." According to the pH chart, the pH value for apple juice is 3.5, which is lower than the pH value for lemon juice (4.0). However, both apple juice and lemon juice have lower pH values than milk (6.5). Therefore, statement C is true.

Statement D: "Maple syrup is more acidic than milk but less acidic than apple juice." The pH value for maple syrup on the chart is 7.0, which is higher than the pH value for milk (6.5). However, it is lower than the pH value for apple juice (3.5). Therefore, statement D is false.

In conclusion, the correct statement is C: "Apple juice is more acidic than lemon juice but less acidic than milk."
