The pH of solutions A, B, C, D are respectively 9.5, 2.5, 3.5, 5.5, The most acidic solution is — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Out of the given values of pH, lesser the value means more acidic. Because, an acid has always pH <7. Therefore, pH=2.5 is most acidic in nature. 47. The pH of a 0.005 molar aqueous solution of Sulphuric acid is approximately (a) 0.005 (b) 1 (c) 2 (d) 0.1 From the given conditions, we know that- + 2 4 + + pH log[H for H SO n=2 Thus H 0 2 ] .01 and, log[H log 0.0 ] 1 =2.0 pH
