pH = - log10[H+] so 2.52
It depends on the concentration but this would be pretty acidic - pH of 0 -1 .
1.70
pH=1
By definition pH = -log[H+], so pH = -log(4.9*10-4) = 3.31Only at 25oC: pOH = 14.00 - pH, so 14.00 - 3.31 = 10.69 = pOH
-log(0.1 M) = 1 pH
It depends on the concentration but this would be pretty acidic - pH of 0 -1 .
pH=-log[H+] pH-log(1.2x10^-3) pH=2.92 since the the pH plus the pOH is always equal 14 14-2.92=11.08 so the pOH is 11.08
1.70
pH=1
The presence of an acid lowers the pH of the solution in water.
By definition pH = -log[H+], so pH = -log(4.9*10-4) = 3.31Only at 25oC: pOH = 14.00 - pH, so 14.00 - 3.31 = 10.69 = pOH
The pH is under 7.
The pH of water increase.
-log(0.1 M) = 1 pH
A pH=11 is a pH of a basic solution; for example a solution of sodium hydroxide in water.
It depends what you mean by water solution. If it's a solution of something else in water, it depends on the solute. If you mean just water, it's pH 7.
7.0, or the pH of water.
