Concentration of H+ can have a varied effect on the nature of the solution. H+ ion concentration increases, the solution becomes more acidic, while a decrease of H+ ion causes an increase in the basicity of the solution.

When pH value is less than 7 it indicates an acidic solution, while greater than 7 it indicates a basic solution. Therefore, the solution A with pH = 6 is acidic and has more hydrogen ion concentration than the solution B of pH=8 which is basic.

When an acid gets diluted, the concentration of hydronium ions (H3O+) per unit volume decreases. This means that the strength of the acid decreases when it gets diluted.

Dissolving an acid in water is an exothermic reaction, it is always recommended that acid should be added to water, in this case heat produced is not sufficient to burn out, if we add acid to water then it is possible that because of the large amount of heat generated, the mixture splashes out and cRead more

HCl or HNO3 shows acidic character on aqueous solution because hydrogen ions dissociation always occurs in the presence of water. Hydrogen ions (H+) when combined with H2O to form hydronium ions (H3O+). The reaction is as follows: HCL(aq) → H+ + CL- H+ + H2O → H3O+ Whereas aqueous solutions ofRead more

Whereas aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Therefore they do not show acidic character.

See lessDo basic solutions also have H+(aq) ions? If yes, then why are these basic?
Yes, the basic solution also has H+ ions. However, H+ concentration is less as compared to the concentration of OH− ions so the solution is basic.
