What is the concentration of undissociated acid if the hydrogen-ion concentration is 0.0001 M and the acid dissociation constant is 0.0000001?
The equation is acid + water equalizes into hydronium and conjugate base, and Ka (acid dissociation constant) is products divided by reactants. If the Acid = (H+)(base)/Ka, then the acid concentration is (H+)(H+)/Ka, or (0.0001)(0.0001)/0.0000001, which equals 1M.
What is the the word equation for hydrochloric acid with sodium hydroxide?
Sodium hydroxide plus hydrochloric acid equals sodium chloride plus water.
Hydrochloric acid plus sodium hydroxide equals?
sodium chloride and water
What is the word equation for the chemical reaction between alluminium hydroxide and hydrochloric acid?
Aluminum hydroxide plus hydrochloric acid equals( produces ) aluminum chloride plus water.
An acid has Ka equals 2.5 x 10-4 what is the Kb for the conjugate base of this acid at 25C Kw equals 1.0 x 10-14 at 25C?
4.0 x 10-11

Which is a conjugate acid base pair in the following equation HS- plus H2O equals S-2 plus H30?
This is a Bronsted question. Hs- is the acid in this which makes H2O a base. Therefore S-2 is the conjugate base and the H3O+ hydronium ion is the conjugate acid.
What is the pH of a solution with H3O plus equals 1 x 10-9M?
pH = -log(hydronium concentration) [Hydronium is H3O.-log(1 x 10-9) = 9
What is the pH of an aqueous solution with the hydronium ion concentration h3o plus equals 4 x 10-13m?
p = -log[H+] = 12.4
Does a solution that has pH equals 7 has the same concentration of hydronium ions as a solution that has pOH equals 7?
Yes, if both solutions are at 25oC then in both solutions this is valid: pH + pOH = 14.0
What is the pH of an aqueous solution with the hydronium ion concentration H3O plus equals 2 x 10-14 M?
13.7 take the negative logarithm
What percentage solution equals a 1 normal solution of sodium hydroxide?
Sodium hydroxide 1 N (normal solution) solution has a concentration of39,99710928 g/L (rounded 40 g/L) or 4 g/100 mL sodium hydroxide in water.
How do you rationalise the denominator?
It depends on what the denominator was to start with: a surd or irrational or a complex number. You need to find the conjugate and multiply the numerator by this conjugate as well as the denominator by the conjugate. Since multiplication is by [conjugate over conjugate], which equals 1, the value is not affected. If a and b are rational numbers, then conjugate of sqrt(b) = sqrt(b) conjugate of a + sqrt(b) = a - sqrt(b), and conjugate of a + ib = a - ib where i is the imaginary square root of -1.
