Acid and Base
|
Detailed explanation-1: -Acids have a large H+ concentration, which translates to a small pH value. Bases have very little H+. Basic solutions have large pH values-greater than pH 7. While pH values have been measured as low as-3.6 and as high as 17.6, most solutions encountered in nature range between pH 0 to pH 14.
Detailed explanation-2: -Since a pH of 3 is three numbers higher than a pH of 6, we can find the change in acidity by taking 10 to the third power. The solution with a pH of 3 is 1000 times more acidic than the solution with a pH of 6.
Detailed explanation-3: -pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
Detailed explanation-4: -Distilled water has a neutral pH of 7. Molecules are made of atoms and are generally considered neutral, meaning they do not have a positive or negative electrical charge. Water is an example of a neutral molecule made of one oxygen and two hydrogen atoms. A neutral molecule is considered stable and happy.
