Base your answer on the information below. Some carbonated beverages are made by forcing carbon dioxide gas into a beverage solution. When a bottle of one kind of carbonated beverage is first opened, the beverage has a pH value of 3. After the beverage bottle is left open for an hour, the hydronium ion concentration in the beverage solution decreases by 10 times of the original concentration. Determine the new pH of the beverage solution.

The question is incomplete, the complete question is;

Some carbonated beverages are made by forcing carbon dioxide gas into a beverage solution. When a bottle

of one kind of carbonated beverage is first opened, the beverage has a pH value of 3.

After the beverage bottle is left open for several hours, the hydronium ion concentration in the beverage

solution decreases to 1/1000 of the original concentration. Determine the new pH of the beverage solution.

Answer:

6

Explanation:

Recall that

pH= -log[H3O^+]

Hence, [H^+] when the drink was first opened;

3 = -log[H^3O+]

[H^+] = Antilog(-3)

[H30^+] = 1 * 10^-3

Since [H3O^+] decreases to 1/1000 times its original value;

New [H3O^+] =  1 * 10^-3 * 1/1000 = 1 * 10^-6

Hence,

New pH = -log[1 * 10^-6]

New pH = 6
