Does tomato juice and lemon have acid?

Yes, both tomato juice and lemon juice contain acids.

- Tomato juice: Tomatoes are acidic, with a pH level of around 4.3. The main acid in tomatoes is citric acid, which is also found in citrus fruits. Tomatoes also contain malic acid and oxalic acid.

- Lemon juice: Lemons are very acidic, with a pH level of around 2.5. The main acid in lemons is citric acid, which is also found in tomatoes and other citrus fruits. Lemons also contain malic acid and ascorbic acid (vitamin C).

When tomato juice and lemon juice are mixed together, the acidity of the mixture increases. This is because the citric acid, malic acid, and oxalic acid in the tomato juice react with the citric acid and ascorbic acid in the lemon juice to form new acids. The new acids that are formed are even more acidic than the original acids.

The acidity of tomato juice and lemon juice can have a number of health benefits. For example, the acids in these juices can help to improve digestion and absorption of nutrients. They can also help to boost the immune system and protect against infection. However, the acidity of these juices can also cause problems for some people. For example, people with acid reflux or other digestive problems may experience discomfort when they drink tomato juice or lemon juice.
