Question

The pH of lemon juice is:
A. \[4.2\]to \[4.4\]
B. \[10.2\] to \[11.4\]
C. \[6.2\] to \[6.8\]
D. \[2.2\] to \[2.4\]

Answer 1

Hint: Lemon juice is a flexible substance with applications for everything from hair care to baking to family cleaning. Lemon juice can lighten hair, sour milk and help recuperate an irritated throat. It's a typical family staple and is a component of numerous items, regardless of whether for its chemical properties or just its new fragrance.

Complete step by step answer:
Lemon juice contains two acids. The juice is about \[5 - 8\% \] citric acid, which accounts for the tart flavour. Lemons also contain ascorbic acid, also known as vitamin C.
Lemons are extremely acidic. Any compound with a pH under \[7\] is viewed as acidic. Lemon juice has a pH of around\[2.0\], going somewhere in the range of \[2\] and\[3\]. To place that in context, the pH of sulfuric acid (sulfuric corrosive) is\[1.0\], while the pH of an apple is about\[3.0\]. Vinegar (a feeble acidic corrosive) has a pH equivalent to lemon juice, around\[2.2\]. The pH of soda is about\[2.5\].
So, Lemon is an acidic organic product with a pH going from \[2\] to\[3\], more precisely \[2.2\]to \[2.4\](option D is correct)

So, the correct answer is Option D.

Note: The acids in lemons are citrus extract, which makes lemons tart, and ascorbic acid, which is vitamin C. Since they are acidic and high in sugar, gnawing into lemons can harm tooth enamel. The pH of the blood is maintained between \[7.35\] and\[7.45\], regardless of how much lemon juice you drink.
