pH = -log10(Ka) - log10([HA]/[A-]) = 3.41 -log10(1.35) = 3.41 - 0.1313 = 3.28
A line of reasoning showing more steps is: By definition, Ka = [H+][A-]/[HA], where the brackets indicate molar concentrations. Dividing both sides of this equation by [A-]/[HA] and substituting the numerical values given results in [H+] = (10.92 X 10-3)(3.887 X 10-4)/(8.07 X 10-3) = 5.260 X 10-4. The log of 5.260 =0.7210, so the pH of this solution is - (-4 - 0.7210) = 3.28, to the justified number of significant digits (limited by 8.07).
no it doesn't.dissolving or making a solution of an acid makes a more dilute solution of the acid.
Vinegar is a dilute solution of acetic acid and is created by diluting concentrated acetic acid 20 fold to create a 5% acid solution.
It would be named as a dilute solution of a weak acid.
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt

The mole fraction must be calculated in moles solvent over moles solution. So, 3.4 grams sulfuric acid equals .0347 moles sulfuric acid. 3500 mL water equals 3500 g water equals 194 mols. .0347 mols/(.0347+194) = 1/5591.77 mols/mol

The name of HF in solution is hydrofluoric acid.

When an acid solution is mixed with a basic solution, there will be a neutralization reaction in which hydrogen ions from the acid will combine with hydroxide ions from the base, to form water.
The presence of an acid lowers the pH of the solution in water.
HNO2 (aq) is nitrous acid in solution.
a water solution of a strong acid is what?
This depends on the acid.
Hydrochloric acid as this acid disassociates fully in solution while ethanoic acid is a weak organic acid that disassociates at only about 1% in solution.
