The ph of coffee is times greater than the ph of pure water. a) 2 b) 10 c) 100 d) 200

It would be 100 times greater if you are going from a pH of 5 to 7

Option (C) is the correct answer.

Explanation:

It is known that pH is a measure of acidity or alkalinity of a solution. When pH is less than 7 then the solution is acidic in nature and when the pH is more than 7 then the solution is basic in nature.

Pure water is neutral in nature and it has a pH of 7, that is, it is neither acidic nor basic in nature.

Whereas coffee is acidic in nature as it has pH of 4 to 5 which is very acidic as compared to pure water if we go from 5 to 7 on a pH scale.

So, we can conclude that the pH of coffee is 100 times greater than the pH of pure water.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
