Answer:
The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.
Explanation:
The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.
A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
The preservation technique that
attempts to remove moisture is dehydration or drying of foods. Many types of
food such as meat, fish are preserved for an unlimited period by removing the
moisture. This way, the growth of microorganisms in the food is hindered. Dehydration
is one of the oldest methods of food preservation. Equipment such as cabinet driers
and vacuum driers are used in dehydration.
There are several ways you can categorize things. This is an example of how I would put animals in order
1. Porifera (sponges)...they consist of a simple cell arrangement
2. Coelenterata (e.g Jellyfish) have an actual tissue
3. Platyhelminthes they are more complex and have muscles
4. Insects. They have several organs that and a simple brain
