[H3O+]= Kw/[OH-] = 1.00*10-14/6.70*10-2 =1.49*10-13 M
pH= -log [H3O+] = -log (1.49*10-13)=12.8
If something is a 0-6 on the pH scale it is an acid solution
0-6 and everything less than 7 (grade 7 science)
pH is related to the activity of ions H+ in a solution. A pH under 7 is acidic, pH=7 is neutral and a pH over 7 is basic.
The maximum value for pH is 14, which corresponds to a highly basic solution. This is because pH measures the concentration of hydrogen ions in a solution on a scale from 0 to 14, with values above 7 indicating alkalinity.
A purple solution in universal indicator indicates an alkaline solution with a pH of 14
Yes, a concentrated solution of NaOH and KOH may have pH=14
The pH of a 6M HCl solution is 0.
The pH of a solution containing 6M HCl is 0.
0 to 7
Neutral solution: pH =7Acidic solution: pH7.
The unit for pH in a solution is a dimensionless unit that measures the acidity or basicity of a solution on a scale from 0 to 14.
If something is a 0-6 on the pH scale it is an acid solution
The lowest possible pH value that can be measured in a solution is 0.
A pH of 0-6 indicates an acidic solution. pH is a measure of how acidic or basic a solution is on a scale of 0-14, with values below 7 indicating acidity.
The scale is from 0 to 14. 0 is ACID and 14 is BASE The pH of a perfect neutral solution in water is 7.0 (at 25oC).
The scale of pH is between 0 and 7.
The pH of a 1N HCl solution can be calculated using the formula pH = -log[H+], where [H+] is the concentration of H+ ions in the solution. For a 1N solution of HCl, the concentration of H+ ions will be 1M, so the pH will be -log(1) = 0.
