Ph of 10–8 m hcl solution is nearly
WebWhat is the pH of 8 x 10^-8 M HCl? Expert Answer 91% (65 ratings) This is a solution of HCl. The solution is acidic. The ph must therefore be less than 7.00If you take HCl to dissociate completely , then [H+] = 8*10^-8MIf you apply the formula:pH = -log [H+]pH = -log 8*10^-8pH = 7.097This answer must be wrong becau … View the full answer WebApr 11, 2015 · So if with a strong monoacid you find $\mathrm{pH}=6.8$ with this formula the result is not correct and you have to make an other approximation or reasonning! Here we have $\mathrm{pH}=-0.69<6.5$ so you find a reasonable answer. And in water $\mathrm{pH}$ is between $0$ and $14$ so your solution is at $\mathrm{pH} \approx 0$

Web10 -8 M indicates a very dilute solution. Thus, H + ions of water cannot be ignored. But dissociation of water is suppressed due to common ion effect. ∴ [H +] ≠ 10 -7 M but less than 10 -7 M. α α H A 2 O ↽ − − ⇀ H A + ( 10 A − 8 + α) + OH A − α K w = [H +] [OH –] = (10 –8 + α) α ∴ α 2 + α × 10 -8 - 10 -14 = 0 WebApr 10, 2024 · Erlotinib’s aqueous solubility is pH-dependent; it is less soluble at neutral pH but more soluble at acidic pH (~ below 5). Erlotinib HCl, marketed under the brand name Tarceva, is prescribed as a single film-coated orally administered tablet at strengths of 25–125. Erlotinib HCL has a maximum solubility of around 0.4 mg/mL at a pH of ~ 2 .
WebTo calculate the pH of an aqueous solution you need to know the concentrationof the hydronium ion in moles per liter (molarity). The pH is then calculated using the … WebCalculate the pH of 10 -8 M HCl. If we use the relation, pH = – log [H 3 O + ], we get pH equal to 8. But this is not correct because an acidic solution cannot have pH greater than 7.
