What is the pH of hydrogen peroxide of 10 percent to 12 percent?
The pH of hydrogen peroxide at concentrations of 10% to 12% is around 3.0 to 4.0. It is considered acidic.
What is the pH in Drano?
To answer this question we would need to know the type of drain cleaner you are referring to. If you are talking about liquid drain cleaner it has a pH of 14. But the pH ranges from 13 to 14 depending on the type.
How does a pH reading of 5 differ from 6?
It is 1 less. Stupid. Just kidding, remember what does the p stand for in pH? POWER of hydronium. PH is -log[H3O+], so a decrease would mean a higher concentration of Hydronium. Remember it's a logarithmic scale, so a change of 1 means a change of 10 times.
Can pH indicator give accurate pH reading for solution?
An accurate measurement is made with a pH-meter; pH-papers make only approximative determination.
Why must the magnetic stirrer be stopped each time before reading the pH?
The magnetic stirrer must be stopped before reading the pH because the movement of the stir bar can cause fluctuations in the solution that could affect the accuracy of the pH measurement. Stopping the stirrer allows the solution to come to rest, giving a more stable reading of the pH.
What is the pH of drano?
Drano has a high pH level, typically around 14, due to its strong alkaline ingredients such as sodium hydroxide. This high pH allows it to effectively dissolve clogs in drains by breaking down organic materials. It is important to handle Drano with care and avoid contact with skin or eyes due to its caustic nature.

Is a pH reading of 7 is an acid?
7 is neutral. Above is alkaline and below is acidic. A pH of 8 means the water is 10 times more alkaline than at 7. A pH of 6 means it is 10 times more acidic than at 7.

What will give the most accurate pH reading?
A calibrated pH meter will give the most accurate pH reading. Regular calibration ensures that the pH meter is accurately measuring the pH level of a solution.
A 10 percent increase in the level of carbon dioxide in the blood will?
Will decrease the blood pH causing increased ventilation.
HA ---- H A- If only 4.2 percent of the acid HA dissociates in solution what is the pH of a 8.73 x 10-4 M solution of HA?
-log(8.73 X 10^4 M) = 3.06 pH
What is a acidic pH?
Acidic pH is a reading of between pH7 (neutral) and pH 0 (highly acidic).
How you standardize pH meter?
Standardize the pH meter using a buffer solution of known pH value.Basically take buffer of pH value 4.Then set zero reading in the pH meter.Now remove unknown buffer solution.(take care with atmospheric temperature.)
Is a single unit change on the pH scale equivalent to 1 percent change in hydrogen ion concentration?
No, a single unit change on the pH scale represents a tenfold change in hydrogen ion concentration, not a 1 percent change. For example, moving from a pH of 5 to a pH of 4 means the hydrogen ion concentration increases by a factor of 10.
How can you test a substance to see if it is an acid or a base through pH meter?
To test if a substance is an acid or a base using a pH meter, simply dip the pH meter probe into the substance and observe the pH reading. A pH reading below 7 indicates an acid, while a pH reading above 7 indicates a base.
