Webb31 aug. 2024 · We know that HCI solution is acidic whatever may be the concentration of HCI i.e, the pH value should be less than 7. In this case the concentration of the acid is very low (10-7 M). Hence the H3O+ (10-7 M) formed due to the auto ionisation of water cannot be neglected. So, in this case we should consider [H3O+] from ionisation of H2O

WebbOsmotic pressure is the lowest pressure that inhibits the inward flow of a pure solvent into a solution that is separated from it by a semipermeable membrane. The quantity of solute particles affects osmotic pressure. It varies in proportion to the solution's molarity. So, this is the correct option. π π π = iMRT. Webb12 dec. 2024 · The definition of pH is "the negative log of the hydrogen ion concentration." This can be written as −log 10 c, where c is the hydrogen ion concentration in moles per liter. So we need to find the concentration of H + in 6.2 x 10-11 M HCl. HCl is a strong acid, so it will completely dissolve in water, especially with such a low concentration.
