Question Which of the following statements is true ? (You can select multiple answers if you think so) Your answer: Actual yield is calculated experimentally and gives an idea about the succeed of an experiment when compared t0 theoretical yield. In acid base titration experiment our scope is finding unknown concentration of an acid or base_ In the coffee cup experiment; enctgy ' change is identified when the indicator changes its colour. Pycnometer bottle has special design with capillary hole through the stopper which enables air bubbles to escape from the bottle in order to fill same volume of the Iiquid into the botrle in every fill: Whenyou want t0 determine melting point of & solid in the laboratory: the colour of the solid changes and temperature is constant in the mel lting poinc The reason of dropping "water+alcohol" solution into the heating beaker in saponification is preventing the bubbles flowing out of the beaker: Next Pausc [cst
