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.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
