Webbwhile solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a … Webb7 apr. 2024 · 10 − 8 M HCl solution is 6.98. Therefore, the correct option is C. Note: When we calculate the pH using the relation p H = − log [ H 3 O +], the pH obtained is 8 but the value of acid solution cannot be more than 7.

Webb4 apr. 2024 · Hint:To solve this we have to calculate the hydrogen ion concentration of aqueous solution of ${\text{HCl}}$ at the given temperature.The ionization constant of water i.e. ${{\text{K}}_{\text{w}}}$ is given to us. From the given values calculate the concentration of hydrogen ion due to ${\text{HCl}}$ and water. then find the total … WebbThe pH of N /10H Cl is : 2168 50 AFMC AFMC 2001 Report Error A 3 B 4 C 2 D 1 Solution: H Cl is a strong acid hence, it is 100% under all concentrations. [H 3O+]of 10N H Cl = 101 = 10−1M pH = −log[H 3O+] = −log(10−1) = 1 Webb10-8 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. poppins typography
