0.2 mol of HCL will give 0.2 mol of H+ ions (strong acid; so full
ionization in water), same goes for 0.25 mol NaOH (strong alkali) that
will give 0.25 mol. of OH-.
H+ + OH- -> H2O
So effectively there'll be 0.05 mol of OH- after mixing 1 mol of each
HCL & NaOH, which translates to 0.025mol of OH- for every mol of the
mixture.
pH = 14 - log10(OH-) = 12.4

What is the pH of solution with 100 ml 0.2 molarity hydrochloric acid with 0.25 molarity sodium hydroxide at the equivalence point?
Strong acid with strong base always ends with neutral water and the resulting ions Na+ and Cl-, both neutral as well!
0.0255 mol potassium hydroxide was dissolved in water to yield 10.0 mL of solution what is the molarity of the solution?
Molarity = Moles/Unit VolumeSo here Molarity = (0.0255) / (10-2) = 2.55 M
When a formic acid solution is titrated with lithium hydroxide will the solution be acidic neutral or basic at the equivalence point?
basic
A solution of NaOH contains 20g of this compound in 2dm3 of this solution . What is molarity of this solution?
This sodium hydroxide solution has a molarity of 0,25.
What is the OH- of a 4.0 x 10-4 M solution of CaOH2?
The concentration of the OH- is 8.0 x 10-4 In terms of molarity, since the hydroxide is double that of the calcium, double the molarity of the solution.

What is the pH value of ammonium hydroxide solution?
It depends on the molarity of the solution
What is the molarity of 2.0 L sodium hydroxide solution containing 10.0 grams solute?
The molarity is 0,125 M.
Barium hydroxide contained 2.74g in 100cm of water titration of 20cm required 18.7cm of a hydrochloric acid solution for complete neutralization what is the molarity of the barium hydroxide?
Barium Hydroxide: Mass: 2.74g. Mr = 171. Moles = Mass (g)/Mr Therefore - 2.74/ 171 = 0.01602339181mols.
