Question

Solution 1 has a pH of 6.5. When Solution 2 is poured into Solution 1, the new solution has a pH of 5.2. What must be true of Solution 2?


It contains no hydroxide ions.

It is more acidic than Solution 1.

It is a basic solution.

It had a pH of 6.5.

Answer 1

I just answered on my test. the answer is B.

Answer 2

The statement, that describes which must be true of Solution 2 that poured into Solution 1 with pH of 6.5 is "It is more acidic than Solution 1."

What is pH?

A solution's pH is a measure of its hydrogen ion concentration, which is a measure of its acidity. In other terms, pH is a scale that specifies the acidity or basicity of an aqueous solution.

The scale ranges from zero (the most acidic) to fourteen (the most basic). The pH scale above shows that pure water has a pH value of 7. That is, pH values less than 7 are acidic, while pH values greater than 7 are alkaline (basic). As a result, solution 2 is acidic and contains more hydrogen ions than solution 1, because an acidic solution has a pH value less than 7.

Hence the correct answer is more acidic than Solution 1.
