20 ml of 0.5 N HCl and 35 ml of 0.1 N NaOH are mixed . The resulting solution willA. be neutralB. be basicC. turn phenolphthalein solution pinkD. turn methyl orange red |

Answer» Correct Answer - D 20 ml of 0.5 N HCl contain `20xx0.5` milli eq. = 10 milli eq. of HCl . 15 ml of 0.1 N NaOH contains `35xx0.1` milli eq = 3.5 milli eq of NaOH . Thus, 3.5 milli eq of NaOH will nutralize 3.5 milli eq of HCl. (10-35)= 6.5 milli eq of HCl will be left. Hence, solution will be acidic and it will turn methyl orange red. |
