Dr. bunsen has a problem—he stored a rack of six bottles filled with clear colorless liquids too close to a heat vent and the labels fell off of each of the bottles. he needs your in order to correctly identify each of the solutions. below is a list of the solutions:  pure di water  0.10 m agno3  0.20 m hcl  0.20 m hno3  0.20 m koh  0.50 m nahco3 we are provided with ph paper and phenolphthalein

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
