pH=-log[H+]
pH-log(1.2x10^-3)
pH=2.92 since the the pH plus the pOH is always equal 14
14-2.92=11.08 so the pOH is 11.08

Are there any differences between pH meter and litmus paper recordings?
Litmus papers can only be used to determine whether the solution is acidic or basic. But from pH meter, the pH range of the solution can be determined.
A 20.0ml sample of 0.800 m Hbr solution is titrated with 0.800 m NaOH solution calculate the pH of the solution after these volumes of base are added 12.5 ml 18.7 ml 20.0 ml 29.5 ml and 34.2?
Looks as if you will need to calculate the pH of the final solution. The formula you need will be [H+] = 1 x 10-6 M.
What is the best method to use to determine the pH of a solution?
Using a calibrated pH-meter with correction for temperature and slope.
What are pH ions?
pH is not an "ion". it stands for Potential Hydrogen.pH is a scale ranging from 0-14. it gives an idea about strength of solution. pH=7...neutral pH7...basic
What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
What is the Ph of a 0.0030 M HBr solution in water?
pH = - log10[H+] so 2.52
What property of the solution to determine if it's an acid or a base?
To determine if the property is an Acid the solution must be less than pH 7. and to determine if the property is a Base the solution must be greater than pH 7.
To figure out the exact pH of a solution you'll need to determine the?
You need to determine the percent of hydrogen (pH) molecules in the solution.
A solution of HBr has H plus equals 2.1 x 10-6 What is the pH of this solution?
1.70
What are some ways to determine the pH of a liquid?
The easiest way to determine the pH of a solution is to use a pH meter.
What is the pH of 0.10 M HBr?
pH=1
What electronic divide is used to determine the pH of a solution?
Ph meter
An electronic device used to determine the pH of a solution?
pH meter
How do you determine the pH of a solution?
lithmus paper
Is rulers used to determine the pH of a solution?
no
What is the relation between pH value and nature of the solution?
The nature of the solution be it acidic or basic will determine the PH value of the given solution.
A solution of HBr has H 2.1 x 10-6 What is the pH of this solution?
By definition pH = -log[H+], so pH = -log(4.9*10-4) = 3.31Only at 25oC: pOH = 14.00 - pH, so 14.00 - 3.31 = 10.69 = pOH
