What is the molarity of H3O plus in an aqueous solution of methanoic acid if its pH is 5.5?
The pH can be calculated using the formula pH = -log[H3O+]. Rearranging, [H3O+] = 10^(-pH). Therefore, [H3O+] = 10^(-5.5), which gives a molarity of approximately 3.16 x 10^(-6) M in the aqueous solution.
What is the pH of iodine?
Iodine does not have a pH since it is not an aqueous solution. pH is a measure of the concentration of hydrogen ions in a solution.
In aqueous solution what pair of compounds in equimolar concentration best represents a buffer system for control of pH?
A weak acid and its conjugate base in equimolar concentration would best represent a buffer system for controlling pH in aqueous solution. For example, a solution containing equal amounts of acetic acid (CH3COOH) and sodium acetate (CH3COONa).
Is NaNO3 a strong or weak acid or strong or weak base?
NaNO3 is a salt composed of a strong acid (HNO3) and a strong base (NaOH). Since both the acid and the base are strong, NaNO3 dissociates completely in water to form Na+ and NO3- ions. Therefore, NaNO3 is considered a neutral salt and does not act as either an acid or a base in aqueous solution.
What pH do Alkalis have?
Any aqueous solution that has a pH value greater than 7 can be considered alkaline. A strongly alkaline aqueous solution usually has a pH of at least 10, and aqueous solutions of very strong alkalies can have a pH range above 13.

What pH is your hair?
Dry hair has no pH. Only aqueous solutions have pH's. When hair is in an aqueous solution it normally has a pH of 4.5 to 5.5

What is ammonia's pH value?
A 1.0 M aqueous solution has a pH of 11.6
How many liters of water must be added to 1 liter of an aqueous solution of hcl with a pH of 1 to create an aqueous solution with pH of 2?

What is the pH of an aqueous solution C6H12O6?
The pH of a solution of C6H12O6 (glucose) is neutral at pH 7 since it does not directly contribute to H+ ions in solution.
Is NaNO3 acidic neutral or basis?
Sodium nitrate (NaNO3) is a neutral salt. When dissolved in water, it will not significantly affect the pH of the solution.
Is Lithium chloride aqueous solution acidic or basic?
Lithium chloride aqueous solution is neutral. It will not significantly alter the pH of the solution.
