Hint: To answer this question we should note that the pH of a solution is a measure of the molar concentration of hydrogen ions in the solution. And this concentration determines the acidity or basicity of the solution. The letters pH stand for power of hydrogen.
Complete step by step solution:
To answer this question, we should note that lemons are extremely acidic. It should be noted that if a chemical has a pH less than 7, we should consider it acidic. We should note that lemon juice contains two acids. We should note that the juice is about 5-8% citric acid, which accounts for the sharp taste to the tongue. Lemons also contain ascorbic acid, also known as vitamin C.
We should know that lemon juice has a pH of around 2.0, ranging between 2 and 3. If we want to compare, we can compare by keeping others' types of acid in perspective. We should know that pH of battery acid (sulphuric acid) is 1.0, while the pH of an apple is about 3.0. Vinegar is found in our homes and we use it in pickles, this vinegar is known by acetic acid and it has a pH 2.2. The pH of soda is about 2.5. So, from the above discussion, we can say that pH of lemon juice ranges from 2 to 3.
So, from this we can say that option D is correct which states that pH of lemon juice is 2.2 to 2.4.
Additional information:
Now, we should know more important points about lemon juice. We should note that lemons are acidic and if we drink lemon juice it will not affect the pH of our body. And after this it will increase the acidity of urine, as the kidneys pass out the body of excess acid. The pH of the human blood occurred between 7.35 and 7.45. It will be the same, regardless of how much lemon juice we drink. While some people believe lemon juice has an alkalizing effect on the digestive system because of its mineral content, there is no scientific data to support this claim.
Note: We should note that acid in lemon juice will attack tooth enamel. If we eat lemons and drink lemon juice, it can put us at risk for tooth decay. Lemons are not only acidic but also contain a surprisingly high amount of natural sugars, so dentists typically caution patients about eating them.
