Why is the pH meter placed in distilled water before testing each solution?
Not the pH-meter, but the electrode.
Which is the best method for student to identify a solution as an acid or a base?
use litmus paper SI
How does pH value of solution help to predict nature of solution?
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
What does the pH of a solution represents?
The pH indicates how acidic or basic a solution is.
What happen with you mix pH solution with soap?
This depends on the pH value of this solution !
Why is the pH meter placed in distilled water before testing each solution?
Not the pH-meter, but the electrode.
Is cobalt chloride paper the same thing as pH paper?
No. Cobalt chloride paper is used for testing the appearance of wate. Whilst pH paper is used for testing the pH value of a particular chemical/solution.
What evidence is there that the acidity of a solution changes?
There is no visual evidence, necessarily. The major indication would be testing with pH paper, litmus paper, pH meter, etc.
Is gold metal stable in a pH 14 water solution?
It is for at least 5 hours.
What would be the pH of a neutral solution An acid solution A basic solution?
Neutral solution: pH =7Acidic solution: pH7.
Which is the best method for student to identify a solution as an acid or a base?

How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
How does a solution with a pH of 2 compare to a solution with a pH of 7?
A pH 2 solution is 100,000 times more acidic than a pH 7 solution. pH 2 is acidic whereas pH 7 is neutral
What is the pH of resultant solution if solution with pH 3 and pH 8 are mixed?
The pH will be 7.that is, it is neutral
What is the pH value of shampoo solution?
What is the pH of shampoo solution
PH of 4 than a solution with a pH of 5?
a pH of 4 is most acidic than a solution with a pH of 5. In general, the lower the pH, the more acidic the solution is.
How does pH value of solution help to predict nature of solution?
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
