Dilute HCl has higher pH value because it has less number of H+ ions. If an acid in one of its solutions has higher pH value, it means that it is in diluted form.
Which of these has higher concentration of H+ ions..
1M of HCl OR 1M of CH3COOH
Explain the reason why: (i) HCl gas fumes in moist air. (ii) Dilute HCl cannot be concentrated beyond 22.2% by distillation. (iii) Dilute acids are stronger electrolytes as compared to concentrated acid. (iv) Liquid ammonia has no action on litmus while liquor ammonia has an effect. (v) Ammonia is not collected over water. (vi) Pure nitric acid does not dissolve gold or platinum, but aqua regia dissolves them.
