Vinegar is an acid. Soft drinks are slightly acidic. Drain cleaners are highly alkaline. Sodium bicarbonate is somewhat alkaline. The household cleaners TSP and ammonia are alkaline.

To determine if a household food or product is an acid or alkali, you can use pH testing strips which are available at most pharmacies or online. These strips measure the acidity or alkalinity of a substance using a color scale. Here are some common household foods/products that fall into the acid or alkali categories:

Household foods that are acidic:
1. Lemon juice: It contains citric acid which gives it a sour taste.
2. Vinegar: Both white vinegar and apple cider vinegar are acidic.
3. Tomatoes: They contain citric acid, which contributes to their tangy taste.
4. Orange juice: It contains citric acid and has a tangy flavor.
5. Yogurt: Some yogurts can be slightly acidic due to the presence of lactic acid.

Household foods that are alkaline:
1. Baking soda: It is highly alkaline and often used as a leavening agent in baking.
2. Milk of magnesia: It is alkaline and often used as an antacid to provide relief from heartburn or indigestion.
3. Almonds: Almonds are alkaline-producing nuts, although they are generally considered slightly acidic when consumed.
4. Cucumber: They have a high water content and are mildly alkaline.
5. Kale: This leafy green vegetable has an alkaline-forming effect in the body.

Please note that the pH levels of foods/products can vary depending on factors such as ripeness, process of fermentation, or storage conditions.
