Strong alkali.
A strong alkali :)
its 12 and sometimes over.
Some do. But all alkali have a pH value of more than 7.
bleach has 13.
pH 4 = acid pH 12= base
Any strong base, such as NaOH ( sodium hydroxide ), with a molarity of at least...., 0.1 M NaOH =============for instance
The pH of a solution can be calculated using the formula: pH = -log[OH-]. Therefore, for a solution with [OH-] concentration of 10-12 M, the pH would be 12.
A basic pH is over 7.
The pH of a solution with a hydrogen ion concentration of 10^-12 M is 12. pH is calculated as -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter. A hydrogen ion concentration of 10^-12 M corresponds to a pH of 12.
the ph of spot remover is 12
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
A pH over 7 is basic.
