WebApr 4, 2013 · The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red. WebFeb 2, 2024 · Methyl Orange Bromocresol Green Phenolphtalein Solution The correct answer is C. In the titration of a weak acid with a strong base, the conjugate base of the weak acid will make the pH at the equivalence point greater than 7. Therefore, you would … In this case, adding 5.00 mL of 1.00 M \(HCl\) would lower the final pH to 1.32 …

WebAnswer (1 of 2): You need two indicators for this titration since it has two end points at pH 8.5 and pH 3.5. Based on the table below I would suggest methyl orange and phenolphthalein ( phenolphthalein is colourless below pH 8 so it does not interfere with the methyl orange end point) WebMethyl orange and Methylene Blue甲基橙和亚甲基兰溶液 3)methylene blue亚甲基蓝 1.Study on photocatalytic degradation for soluble methylene blue in water by SO_4~(2-) modified nano-sized TiO_2;改性纳米二氧化钛光催化降解水中微量溶解性亚甲基蓝 2.Anodic stripping voltammetric determination of Sn(II) at poly methylene blue/multiwalled carbon … stephanie mcmahon andre the giant
