Explanation:

Step1: Recall pH - value rules

Solutions with pH < 7 are acidic, pH = 7 are neutral, and pH>7 are alkaline.

Step2: Classify lemon juice

Lemon juice has pH = 2.2. Since 2.2<7, it is acidic.

Step3: Classify salt solution

Salt solution has pH = 7. So it is neutral.

Step4: Classify baking soda

Baking soda has pH = 9. Since 9>7, it is alkaline.

Step5: Classify bleach

Bleach has pH = 13. Since 13>7, it is alkaline.

Step6: Classify tomato juice

Tomato juice has pH = 4. Since 4<7, it is acidic.

Step7: Classify gastric juices

Gastric juices have pH = 1. Since 1<7, it is acidic.
