Aph scale with ph values of some aqueous solutions. look at the figure showing the ph values of some familiar aqueous solutions. what is the difference between h+ concentration in an acidic solution such as lemon juice (ph 2) and a basic solution such as household bleach (ph 13)? a ph scale with ph values of some aqueous solutions. look at the figure showing the ph values of some familiar aqueous solutions. what is the difference between h+ concentration in an acidic solution such as lemon juice (ph 2) and a basic solution such as household bleach (ph 13)? the h+ concentration of lemon juice is higher than the h+ concentration of household bleach by a factor of 11. the h+ concentration of lemon juice is higher than the h+ concentration of household bleach by a factor of 1011 (100 billion). the h+ concentration of household bleach is higher than the h+ concentration of lemon juice by a factor of 1011 (100 billion).
