What is the Ka of HClO4?

Ka Acid
Name Formula
Large Perchloric acid HClO4
3.2 * 109 Hydroiodic acid HI
1.0 * 109 Hydrobromic acid HBr

How do you convert pH to Ka?

As noted above [H3O+] = 10pH. Since x = [H3O+] and you know the pH of the solution you can write x = 102.4. It is now possible to find a numerical value for Ka. Ka = (102.4)2 /(0.9 – 102.4) = 1.8 x 105.

What is the pH of hydrochloric acid solution?

1.5 to 3.5

Hydrochloric acid is an essential component of gastric acid which has a normal pH of 1.5 to 3.5. A weak acid or base does not ionize completely in aqueous solution. Ionization of a weak acid (HA) is characterized by its dissociation constant (Ka).

Can you have a negative pH?

It’s definitely possible to calculate a negative pH value. … In practice any acid that yields a concentration of hydrogen ions with a molarity greater than 1 will be calculated to have a negative pH. For example the pH of 12M HCl (hydrochloric acid) is calculated to be -log(12) = -1.08.

Is Ca Oh 2 an acid?

Is calcium hydroxide acidic or basic? Calcium hydroxide also known as slaked lime (with the chemical formula Ca(OH)2) is a source of hydroxide ions when dissolved in aqueous solutions. Therefore this compound is a base.

What is the pH of a 0.015 M Ca OH 2 solution?

So that simply means ph is equal to 14. Minus that 1.52. And guys that’s gonna end up giving us a final pH equal to 12.48.

What is the pH of a 0.02 M solution of sodium hydroxide?

pH of 0.02M of NaOH is 12.30.

What is the pH value of 0.02 m NaOH solution?

Its concentration here is high enough to ignore H3O+ contribution from water so the pH is just -log(0.02) = 1.7. pH + pOH = 14 so the pOH is 12.3.

What is the pH of a 0.02 M sodium hydroxide solution is sodium hydroxide an acid or a base?

The pH of the solution is 12.3. Because sodium hydroxide is a strong base it makes sense that the pH is above 7.

What is the pOH of a 0.02 M Ca OH 2 solution?

….for calcium hydroxide we got [HO−]=0.04⋅mol⋅L−1 … …and so pOH=−log10(0.04)=−(−1.40)=1.40

How do you find the pH of a solution?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].
