Question

Which has highest ph value concentration or diluted solution of hcl?

Answer 1

pH value of any sample depends on the concentration of H+ ions present in the sample , This is proved by the equation: pH=-log(H+)

●Concentrated HCl has more number of H+ ions compared to dilute HCl. Thus, conc HCl is more acidic and it will have a lower pH than dil HCl. Because lower the concentration of H+ ions, higher the pH of sample
