Answer:

24 hours

Explanation:

Frozen foods are foods that were put in a refrigerator. The essence of putting food in a refrigerator is to lower the rate at which microbes cause the spoilage of the food by lowering its temperature considerably.

After 24 hours, microbes must have commenced action on non-frozen ready to eat foods causing them to spoil in not more than 24hours.

The pK of acetic acid is pK = 4.76. For a 0.1 M solution of acetic acid at a pH = 4.76 what is the concentration of [H+]?
spin [16.1K]

Answer:

[H+] = 1.74 x 10⁻⁵

Explanation:

By definition pH = -log  [H+]

Therefore, given the pH,  all we have to do is  solve algebraically for  [H+] :

[H+]  = antilog ( -pH ) =  10^-4.76 = 1.74 x 10⁻⁵
