Thin layer chromatography can use silica plates which are very polar. Will polar or non polar substances have lower Rf values on this plate? ANS -Polar substances - they will have a higher affinity for the silica and thus will not travel as far as the non polar substances A titration of a strong acid with a strong base or vice versa has an equivalence point around what pH? ANS -7 What type of bond is usually disrupted during denaturation of proteins? ANS -H bond Is uracil a purine or...
