Which of the following household substances is likely to have a pH close to 2?

1. Baking soda
2. Milk
3. Orange juice
4. Battery acid

In the pH scale, a lower pH value indicates:

1. Higher acidity
2. Higher alkalinity
3. Neither acidity nor alkalinity
4. A higher temperature

If the pH of a solution is 10, what can you conclude about its acidity or basicity?

1. It is neutral
2. It is acidic
3. It is basic
4. It is impossible to determine from the pH value alone

CHOOSE ONE SUCCESS CRITERIA YOU BELONG TO

I can recognize the pH scale and understand its numerical range from acidic to basic substances.

I can differentiate between strong and weak acids/bases, in terms of pH

I can formulate & justify reason for maintaining optimal pH levels in various real life situations such as agriculture

I need extra time line to learn about PH
