The ph of a solution measures the [h3o+] in the solution. if one solution has a ph of 4 and another solution has a ph of 3, how does the [h3o+] in the two solutions compare?
they are in a 1: 1 ratio.
they are in a 1: 10 ratio.
they are in a 1: 100 ratio.
they are in a 1: 1000 ratio.

The correct answer is:'They are in a 1:10 ratio'.

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution.

Mathematically written as:

The pH of solution-1 = 4

The pH of solution-2 = 3

The ratio of hydronium ion concentrations:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
