Which of the following substances would have a pH greater than 7?*1 pointstomach acidvinegarlaundry detergentlemon juice

The substance that would have a pH greater than 7 from the given options is laundry detergent.

Here's why:

The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic and a pH greater than 7 is basic (or alkaline).

1. Stomach acid is highly acidic, with a pH typically ranging from 1.5 to 3.5, so it's less than 7.
2. Vinegar is also acidic, with a pH of about 2.2.
3. Lemon juice is another acidic substance, with a pH of around 2.

On the other hand, laundry detergent is a basic substance. Most laundry detergents have a pH that is somewhere between 9 and 11, depending on the exact formulation. So, laundry detergent has a pH greater than 7.
