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.
1-14
1 TO 14
- log(1 X 10^-5 M) = 5 14 - 5 = 9 pH ----------
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
The pH scale measures how acid something is. It goes from 1 to 14, 1 being the most acidic and 14 the least acidic.
0-14, 7 is neutral, anything greater than 7 is a base, anything less than 7 is an acid
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.
