Bromophenol blue is another common acid-base indicator which changes color from yellow in acidic solution to blue in basic solution. the ph values for this indicator are in a range of approximately 3 to 4.6. instead of using phenolphthalein in the ch3cooh-naoh titration, if bromophenol blue was used, would the calculated molarity of acetic acid be high, low, or the same?

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

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.

the answer is 0.42 is that is an option. this question provides no info
