There is no given pH value for any particular acid. pH is a measure of the concentration of hydrogen ions in an aqueous solution. It depends on both how strong an acid is (how much it ionizes) and how much of it is dissolved in a given volume of water.
However, because hydrochloric acid is a strong acid it will normally produce a very low pH.
A 1M solution of it has a pH of 0. a 0.1 M solution has a pH of 1, a 0.01 M solution has a pH of 2 and so forth until a pH of 7.

∙ 9y agoCarbonic acid has the chemical formula H2CO3. Under normal atmospheric pressure, the concentration of dissolved CO2 is 1.18 E(-5) moles per liter, giving a pH of 5.65.

What is pH value for carbon dioxide?
Gases do not have a pH as pH is a measure of hydrogen ion concentration in solution in water. Carbon dioxide is sparingly soluble in water and mostly forms very weakly ionised carbonic acid. pH will be close to 7.
If a person is not exhaling carbon dioxide which then becomes carbonic acid in the blood is this raising the pH or lowering the pH?
Yes, the presence of carbon dioxide in the blood lowers pH so therefore when it is removed the pH increases. However the act of removing carbon dioxide itself does not affect pH, rather it results because of less carbon dioxide.
What is the pH level of carbon dioxide gas?
The pure and dry carbon dioxide gas has no pH level.
What is discrepancy between the calculated pH and the experimental pH of the buffer solution?
Air. Carbon dioxide from the atmosphere enters the aqueous solution and forms carbonic acid, which increases the concentration of hydronium, thus lowering the pH.
PH of silicon dioxide?
Silicon dioxide is not a reactive solution and therefore pH does not apply to it.

What is the pH of carbon dioxide?
This Depends on the carbonic acid in the solution .
When carbon dioxide is dissolved in water the pH of the solution will?
Decrease
How can you test for magnesium oxide and carbon dioxide?
Carbon dioxide absorbed in water form carbonic acid, H2CO3; the pH become acidic and you can test the solution with a pH paper. A simple test for the magnesium oxide, MgO, is to measure the refractive index (this value is 1,736 for MgO.
What is the solution of a pH lower than the pH of distilled water?
pH value of distilled water would be 5,6 and 7 as interaction with the atmosphere allows carbon dioxide to dissolve into it, forming carbonic acid. salt on its own has no ph value but , when mixed in water the ph value of common salt is 7 and it is neutral.
Why does carbon dioxide have low pH?
As a gas, carbon dioxide does not have a pH. However, it is slightly soluble in water and when it dissolves in water, the resultant solution is slightly acidic. Slightly acidic solutions have a pH less than 7 which is considered "low".

The pH for carbon dioxide?
pH applies only to aqueous systems. Dissolved in water, carbon dioxide is very mildly acidic.
