If I use the dropper to add 10 mL of drink mix to 50 mL of water, what is the
Yuliya22 [10]

Answer:

16.7%

Explanation:

From the question given above, the following data were obtained:

Volume of drink mix = 10 mL

Volume of water = 50 mL

Percentage of drink mix =?

Next, we shall determine the total volume of the solution. This can be obtained as follow:

Volume of drink mix = 10 mL

Volume of water = 50 mL

Total volume of solution =?

Total volume of solution = (Volume of drink mix) + (Volume of water)

Total volume of solution = 10 + 50

Total volume of solution = 60 mL

Finally, we shall determine the percentage of the drink mix in the solution. This can be obtained as follow:

Volume of drink mix = 10 mL

Total volume of solution = 60 mL

Percentage of drink mix =?

Percentage of drink mix = Vol. of drink mix / total volume × 100

Percentage of drink mix = 10/60 × 100

Percentage of drink mix = 16.7%

Write reaction equations to explain how your acetic acid-acetate buffer reacts with an acid and reacts with a base.
guajiro [1.7K]

acetic acid = CH3COOH(aq) , acetate = CH3COO-(aq) and proton = H+(aq)

so...

CH3COOH(aq) <-> CH3COO-(aq) + H+(aq)

this is the dissociation of acid, therefore, it will yield H+ ions in solution, which are ACIDIC

then... for the acetate buffer, recall that

CH3COO-(aq) is a weak conjugate base, so, it can accept H+ if in excess

so

H+(aq) + CH3COO-(aq) <--> CH3COOH(aq)

therefore, addition of excess H+, will form CH3COOH slowly.. i.e. th epH will not increase drstically

Addition of OH- ins, from a strong base:

OH-(aq) + H+(aq) <--> H2O(l)

then, OH- is apdily converted to H2O, which is not basic, so pH won't change drastically.
