pH = -log10[H] so 1.96 x 10-2 = -1.71 so 1.71.
pH + pOH = 14 14 - 1.71 = 12.29

yes
When A balloon has a volume of 10500 liters and the temperature is 15 and degC. If the temperature were -25 and degC what would the volume of the balloon be?
It would be approx 9042 litres.
A student carefully diluted 25.0 ml 0.6 M NaOH solution in 475 ml of distilled water What is the molarity of the diluted solution of base?
Assuming that the 25.0 ml are added to the 475 ml of water, not diluted to that volume:Moles of NaOH in the original 25 ml = 25/1000 x 0.6 = 0.015 moles Final volume = 25 + 475 ml = 500 ml. We have 0.015 moles in 500 ml, so 0.03 moles in a litre, Molarity = 0.03.
How procedure of NaoH are required to prepare 0.25 L of 0.5 M of solution?
25 mL of 10% NaOH + 175 mL of distilled water
Calculate the pH of solution formed when 30cm3 of 0.125m naoh are reacted with 25cm3 of 0.15m hcl at 298k?
No. of mol of NaOH used = 30/1000 x 0.125 = 0.00375No. of mol of HCl used = 25/1000 x 0.15 = 0.00375No. of mol of HCl used = No. of mol of NaOH used.Hence, the resultant solution will be neutral. pH ~ 7.(NaCl formed is a neutral salt, does not undergo any form of salt hydrolysis)

The solubility increase from 38,7 g KCl/100g water to 40,7 g KCl/100 g water.
What is the normality if 25mL of 0.5 N NaOH is needed to neuralize 30 mL of the unknown acid solution?
25 (mL) * 0.5 (N) = 30 (mL) * X (N) X = unknown normality of acid = (0.417 N) = 0.4 N
