WebbCalculation of Ka/Kb: Suppose you had measured the pH of a 0.1 M solution of the weak acid HF, and had found the pH to be 4.0 When HF ionizes, the reaction would be. for which Ka would have the form. If the pH of the solution was measured to be 4.0, then the hydrogen ion concentration must be 1.0 X 10 -4 M. Since one F - ion is produced every ... WebbI dag · On the reaction of HCl with water, HCl completely breaks down to release hydronium and chloride ions. Cl- is the conjugate base. A strong acid leads to the formation of a weak conjugate base. It is believed that the weaker the conjugate base is, the stronger is the acid. For strong acids, the value of pKa is less than -1.74. For HCl, pKa is -6.3.

Webb8 jan. 2016 · As you know, the pH of a solution is simply a measure of the concentration of hydronium ions. pH = −log([H3O+]) So, if you get one mole of hydronium ions for every one mole of hydrochloric acid, you can say that. [H3O+] = [HCl] = 0.001 M. This means that the pH of the solution will be. pH = −log(0.001) pH = 3. Answer link. WebbThe pH of a solution ranges from 1-14, 1-6 are acidic, 7 is neutral, and 8-14 are basic. It is a measure of the amount of hydrogen ion concentration in a solution and any change greater than 0.5 can cause loss of function or death to any organism.
WebbAll right, so the concentration of HCl in our original solution would be, we had 0.000844 moles. All right, divide that by liters. That was 0.0200 liters, right? 20 milliliters is equal to 0.0200 liters. And so we can do our calculation here. So we can take 0.000844, and we can divide that by 0.0200, and we get for our answer here 0.0422 molar. WebbThe pH is −log [H +] = −log (3 × 10 −4) = 3.5, which is significantly less than the pH of 7.00 for a neutral solution.

Find the pKb of BOH: (Given : log 2 =0.3 ) A −3.3 B 3.3 C 6.66 D −6.66 Solution The correct option is B 3.3 BOH + HCl → BCl + H2O 1 mmole 1 mmole 0 Hence, volume of HCl used 10 mL [B+]= 1 20⇒ pH = 1 2=(pKw −pKb−logC) 6 = 1 2(14−pKb−log 1 20)
WebbpH of any acid can be calculated by using the following formula: pH= -log (H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions. Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions. Therefore, 0.01 moles of H2SO4 will give rise to 0.02 moles of H+ ions.
Webbför 2 dagar sedan · The pH value for 0.1 M solution can now be calculated as: pH = – log [H+] = – log [ 3.93 X 10-7 ] = – [ log 3.93 – 7 log 10] = 6.41 As the pH value is less than 7, therefore, it is clear that H2O2 is acidic in nature.
