What is the formula for HClO4?
Nov 21, 2021 · What is the ka for 0.03M Solution of HClO4 for 1.90 PH value. A) 7.2x10^-3 B) 8.27x10^-3 C) 8.27x10^-4 D) 6.27x10^-4 (I keep getting 5x10^-3 when I round all the values to 2 decimal places but it’s not in the options)
How do you find the Ka value?
As noted above, [H3O+] = 10-pH. Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 - 10-2.4) = 1.8 x 10-5.Mar 23, 2018
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).

What is Ka of an acid?
The acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. Strong acids have exceptionally high Ka values. The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates.
Is HClO4 Bronsted Lowry acid?
HClO4 act as Bronsted-Lowry acid as it donates the proton and forms a conjugate base. NH3 acts as a Bronsted-Lowry base as it accepts the proton from HClO4 and forms a Conjugate acid.

What is Ka acid base?
The acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution while the base dissociation constant (Kb) is a measure of basicity—the base's general strength. Ka and pKa. Acids are classified as either strong or weak, based on their ionization in water.
How do you find the Ka value of acids?
Ka=([H+][A−]HA) where [H+],[A−]&[HA] are molar concentrations of hydronium ion, conjugate base and weak acid at equilibrium.Jul 10, 2017
What is the king of acids?
The king of acids is HNO3+3 HCl (aquea regia) because it dissolves gold and platinum. H2SO4 is Sulfuric Acid, no big deal). Perchloric acid (HClO4) is rated as highly corrosive especially at elevated temperatures and used to make rocket fuel.
Which is stronger, perchloric acid or oxyacid?
Perchloric acid is stronger than Periodic acid. While comparing acidic strengths in oxyacids, the larger the oxidation state of the central atom the stronger the acid is and if the oxidation states are same the more electronegative the central atom the stronger the acid is. 20.9K views. ·.

Why is H2SO4 and HClO4 so strong?
:H2SO4 and HClO4,HClO4 is strong because the perchlorate ion form by the removal of hydrogen atom is more stabilised than sulfate ion or in othr words the negtive charge in perchlorate ion is more dispersed as compared to sulfate ion. Sponsored by Grammarly. Fast.
What does ka mean in chemistry?
Ka is defined by the following equation. Simply Ka value indicates how easily the acid loses a proton. If Pka value is high then the acid is weak while Pka value low means the stronger acid. Pka value indicates the strength of the acid.
Which acid has a positive pKa?
Weak acids like carbonic acid , acetic acid etc. have highly positive pKa values, as they are only partially ionised in water. The ability on an acid to release H+ ion is also closely linked to the stability of the resultant conjugate base (A-) of the ionisation process.
What is the ability of an acid to release H+ ion?
The ability on an acid to release H+ ion is also closely linked to the stability of the resultant conjugate base (A-) of the ionisation process. The stabler the conjugate base, the stronger will be the acid. Continue Reading.
Is perchloric acid nucleophilic?
There are two numbers given with references, but both suggest that Perchloric Acid is an extremely strong acid. It provides strong acidity with minimal interference because perchlorate is weakly nucleophilic (explaining the high acidity of HClO4).”. reference: Perchloric acid - Wikipedia.
