I know that pH -value from 1 to 14 why?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
The most alkaline pH is '14'. NB pH ranges from 1(acidic) to 7(neutrality) to 14 ( alkaline).
PH can be less than 0 and it can be more than 14. PH is -log of (H ) concentration. According to this the PH Of 1 M strong acid such as Hcl would be 0. similarly ... 10 M = pH -1 0.1 M = pH 1 0.01M = PH 2 0.001M = PH 3 0.0001M = PH 4 The pH scale is between 0-14 because the solution with which we generally encounter is in 0-14 range.
- log(1 X 10^-5 M) = 5 14 - 5 = 9 pH ----------
1-14
1 TO 14
acid=1-6 nuetral=7 base=8-14 the ph scale goes from 1 to 14
The scale of the pH ( power of Hydrogen or negative logerthermic of Hydrogen ion) is from 1 to 14. If is 1 to 7 the liquid said to acidic. If it is 7 to 14 it is said to basic in character. When we go from pH 1 to 14 acidity reduces. When we come from pH 14 to 1 acidity increases. The same is vice-versa for basic character. Now to for the question how to raise the pH is ? From pH 1 to 14 it means increasing basic character or reducing acidic character. This can by achieved by adding strong basic character chemical to the liquid where pH to be raised Answer by P.Sivakumar, Chennai
0-14, 7 is neutral, anything greater than 7 is a base, anything less than 7 is an acid
The pH scale measures how acid something is. It goes from 1 to 14, 1 being the most acidic and 14 the least acidic.
The pH scale is from 1-14 Strong acids are 1-4
For a 0.1 M HCl solution, all of the HCl molecules will dissociate into H+ and Cl- ions, resulting in a concentration of 0.1 M for H+ ions. Since pH = -log[H+], the pH of the solution is 1. The pOH can be calculated by subtracting the pH from 14, so the pOH would be 13.
