The pH values of (i) 0.1 M HCl (aq), (ii) 0.1 M KOH, (iii) tomato juice and (iv) pure water follow the order.(a) (i) < (iii) < (iv) < (ii)(b) (iii) < (i) < (iv) < (ii)(c) (i) < (ii) < (iii) < (iv)(d) (iv) < (iii) < (ii) < (i) |
Answer» Answer is : (a) (i) < (iii) < (iv) < (ii) pH stands for potenz (power) of hydrogen. The pH values for acidic solution ranges from 0 to 7, for pure water its value is 7 and for basic solution, it ranges from 7-14. As HCl is a strong acid, the pH value will be least. On the other hand, KOH is a strong base, its pH value will be maximum, tomato juice contains citric acid which is a weak acid, so its pH value will be more than HCl, but will be less than H2O and KOH. Thus, the correct order of pH values will be (i) < (iii) < (iv) < (ii) |
