What is the pOH of a 0.02 M solution of HCl?
pH = ? pOH = ? ∴ pH = 1.6990; pOH = 12.3010.
How do you find the pH of 0.02 m?
- The hydroxide ion concentration [OH-] in 0.02M NaOH= [2 x 10-²]
- So. [ OH-] = 0.02 = 2 x 10-²
- Since NaOH is a strong electrolyte (alkali) and is completely ionised even at normal concentrations.
- So pOH= – log(0.02)= 1.6990.
- So pH= 14- pOH.
- pH = 14- 1.6990.
- pH =12.3010.
What is the pH of a 0.01 M HCl solution?
2
Hence, the answer is – option (d) – the pH of 0.01 M solution of HCl is 2. =>pOH = 14 – pH. Note: “pH is a scale used to specify the acidity or basicity of an aqueous solution.
What is the pH of 0.2 M?
Therefore it determines pH of a 0.2M solution of pyridine is 9.24.
What is the pH of a 0.02 M solution of KOH?
The pH of a 0.02 M solution of KOH 12.3.
What is the pH of a 0.02 M solution of sulfuric acid h2so4?
The pH of 0.02 M is 1.4.
What is the pH of 0.02 m of hno3?
Since a complete dissociation occurs for a strong acid such as nitric acid, the concentration of the hydronium ion is also equal to 0.20 M (the same as the concentration of nitric acid). With this, we can now calculate the pH value of the solution. The pH of the solution is equal to 0.70.
What is the pOH of a 0.02 M CA Oh?
….for calcium hydroxide we got [HO−]=0.04⋅mol⋅L−1…and so pOH=−log10(0.04)=−(−1.40)=1.40
How do you make a 0.02 M solution?
Preparation and Standardization of 0.02 M Potassium Permanganate
- Dissolve 3.2 g of potassium permanganate in 1000 ml of water.
- Heat on a water-bath for 1 hour.
- Allow to stand for 2 days and filter through glass wool.
- Standardize the solution in the following manner.
What is the pH of 0.05 M HCl?
As a consequence, the pH of the aqueous solution of HCl is 1.31.
What is H +] if HCl is 0.020 m?
Answer: HCl is a strong acid, it dissociates 100% (I.e. completely): [HCl]F = 0.020 M = [H3O+] So, pH = – log [H3O+] = -log [HCl]F = -log(. 020)=1.70 Voila!
What is the pH of 0.00001 M HCl?
0001 M HCl is the same as saying that 1 *10–4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.
Is 0.1 m HCl a strong acid?
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M.
What is the meaning of 0.1 M solution of HCl?
Therefore, 8.3 ml of 37% HCl in 1000 ml water is required to prepare a 0.1M HCl solution.
What is the pH of 1 M HCl?
In case of HCl (very strong acid) you can assume that it is 100% ionised in H2O. Therefore, pH= -log (molarity). Hi, as professor Thomas Proft said pH= -log[H3O+], thus HCl 1M has a pH=-1, however pH has been defined between 0 and 14, according to the water constant (pK=14).
What is the pH of a 0.2 M solution of sodium acetate?
6.5
Sodium acetate 0.2M – Sodium cacodylate pH 6.5; 0.1M – PEG 8000 30% solution.
What will be the pH of 0.2 M aqueous solution of nh4cl?
-Therefore the pH of the ammonium chloride solution is 5.35.
What is the pH of 0.25 M KOH?
We’re being asked to calculate the pH of a 0.25 M KOH solution. The pH of the solution is 13.4.
What is the pH of a 0.125 M solution of Hno₃?
pH = -lg [H+] = -lg0. 125 = 0.903 (to 3s.
