What is the difference between the concentration of an acid and its strength? 0.1M HCl has pH of 1.0; 0.10M H2SO4 has a pH of 1.0 and 0.1M acetic acid has a pH of 3.0. Which would you say is the weakest? STRONG VS WEAK, CONCENTRATED VS DILUTE. These terms are not interchangeable. Strong vs. weak deal with the amount of ionization.

= 31.25 cm3 of sulfuric acid. Question 46. In a titration, 25 cm3 of a 0.12 M sodium hydroxide solution required 24 cm3 of a sulfuric acid solution for complete neutralisation. Calculate (a) the number of moles of sodium hydroxide consumed (b) the number of moles of sulfuric acid consumed and (c) the concentration of the sulfuric acid solution.

Tooth decay by the pH of saliva changing due to bacteria adjusting pH levels. Formation of Acid Rain (a series of rxn’s must occur) Ex: SO2(g) + H2O(l) → H2SO3(aq) SO3(g) + H2O(l) → H2SO4(aq) Sulfuric Acid. The pOH scale is based on the pH scale & uses the fact that the sum of hydronium ions + hydroxide ions = 14; in other words, pOH = 14 ...

Part 1. Relation of pH and dilution of a strong acid. - Take 5.0mL of 0.1M HCl (a strong acid) and combine it in a large test tube with 10.0mL of distilled water. Mix it VERY WELL. - Take 5.0mL of the diluted acid and combine it in another large test tube with 10.0mL of distilled water. Mix it VERY WELL.

Ka1 can be calculated using the initial concentration of the acid and the initial pH of the solution. If Ka1 is significantly greater than the other ionization constants by a factor of at least 103, the [H3O+1] can be assumed to come essentially from only the first ionization and can be calculated from the initial pH…
