Why is th acid in lemon juice safe to drink but sulphuric not?

Lemon juice:

1. Organic Acids: Lemon juice primarily contains citric acid, a weak organic acid. Citric acid occurs naturally in many fruits and is generally safe for human consumption.

2. pH Level: Lemon juice has a pH level that typically ranges from 2 to 3, which is acidic but not extremely corrosive.

Sulfuric Acid:

1. Strong Mineral Acid: Sulfuric acid is a strong inorganic mineral acid known for its corrosive properties.

2. pH Level: Sulfuric acid has an extremely low pH, usually below 1, making it highly acidic and potentially dangerous to ingest.

3. Corrosiveness: Sulfuric acid can cause severe burns and damage to tissues upon contact due to its high acidity and corrosive nature.

4. Toxicity: Ingestion of even a small amount of concentrated sulfuric acid can be life-threatening and cause severe internal injuries.

In summary, lemon juice's organic acids, such as citric acid, and moderate pH level make it safe for consumption, while sulfuric acid is a strong, corrosive mineral acid with an extremely low pH that can cause severe harm if ingested.
