How does a phenol red-containing solution look if co2 level is low?

vampirchik [111]

Answer:

The variables to be examined in relation to carbon dioxide use are the amount of light exposure and amount of dissolved CO2. Phenol red is yellow/orange under acidic conditions, that is when the pH of the solution is less than 7 (e.g. pH = 6). This occurs when the concentration of CO2 is high.

EXPERIMENT: DETERMINING VOLUME

Tanzania [10]

Explanation:

(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?

(Ans- A) Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.

(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?

(Ans-B) It will work for both regular and irregular shaped objects since both displace equal volumes of water.

(Ques - C) Is one method of measurement more accurate than the other? Why or why not?

(Ans-C) Both are pretty accurate, with some experimental errors which may creep in accidentally.

(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?

(Ans - D) No, the method would not work because sugar being soluble, will dissolve in water.

No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.

(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.

(Ans- E) I learnt about determining volume of different objects from this investigation. (Sorry, I know its not a very thoughtful answer)
