which of the following is not Acidic?
Milk
Saliva
soft drinks
blood
blood
Sra
To determine which of the following substances is not acidic, we need to understand the concept of pH. pH is a scale that measures the acidity or alkalinity of a substance. It ranges from 0 to 14, where 0 represents strong acidity, 7 is neutral, and 14 indicates strong alkalinity.
To find the answer to your question, we can look up the pH levels of each substance and check which one is not within the acidic range. Here are the approximate pH levels of the substances you mentioned:
- Milk: The pH of milk is around 6.7, which is slightly acidic but still closer to neutral than some other substances.
- Saliva: The pH of saliva typically ranges from 6.2 to 7.4, making it slightly acidic or near neutral.
- Soft drinks: Soft drinks are known to be highly acidic. The pH of most soft drinks can range from 2 to 4, which is considerably acidic.
- Blood: The pH of blood is usually between 7.35 and 7.45, making it slightly alkaline or basic rather than acidic.
Based on the pH values, we can conclude that soft drinks are the most acidic substance among the options you provided. Therefore, soft drinks are not considered not acidic. Instead, blood, with a slightly alkaline pH, is the substance that is not acidic.
