(4) Remains the same 47. Equal volumes of three acid solutions ofPH 3, 4 and 5 are mixed in a vessel. Whatwill be the H+ ion concentration in themixture ?(1) 3.7 X10-M(2) 1.1110-(3) 1.11 10-M(4) 3.7.10-M |
| Answer» DEXPLANATION:According to volumetric pricipleV1M1 + V2M2 + V3M3 = V4M4Since the VOLUMES are equal V1 = V2 = V3 = VM1 = 1×10−3 (since pH=3)M2 = 1×10−4 (since pH=4)M3 = 1×10−5 (since pH=5)(V + 1×10−3 ) + (V + 1×10−4 ) + (V + 1×10−5 ) = 3V + M43V + 10−3 (1+10−1 + 10−2) = 3V + M4M4 = 10−3 × (1 + 0.1+0.01) = 1.11 ×10−3 molar. | |
