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 to theoretical yield: In acid base titration experiment; our scope is finding unknown concentration of an acid or base: In the coffee cup experiment; energy change is identified when the indicator changes its colour: Pycnometer bottle has special design with capillary hole through the stopper which enables air bubbles t0 escape from the bottle in order to fill same volume of the liquid into the bottle in every fill When you want to determine melting point of a solid in the laboratory; the colour of the solid changes and temperature is constant in the melting point: The reason of dropping "water+alcohol" solution into the heating beaker in saponification is preventing the bubbles flowing out of the beaker
