What is the pH of 1n NaOH solution?

pH of 1 N NaOH solution at 25°C is e answer: 0.

Which one of the following is the pH of 0.010 m NaOH solution?

pOH=−log[OH−]=−log(0.010)=2 p O H = − log ⁡ [ O H − ] = − log ⁡ . Finally, we evaluate the pH thus: pH=14−pOH=14−2=12 p H = 14 − p O H = 14 − 2 = 12 .

What is the pH of 0.01 M 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 a 0.1 M nh3 solution?

The pH = 11.3 .

Is 1 m NaOH acidic or basic?

NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution.

Is 1 M HCl acidic or basic?

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 0.1 m NaCl solution?

Since NaCl is a salt of strong acid and a strong base it is a neutral salt it’s pH is 7.No matter what it’s concentration is..

What is the pH of 1.00 M HCl?

0
Thus, we obtained that pH of the 1M solution of HCl is 0.

What is the pH of a 0.01 M solution of sodium hydroxide NaOH?

So, a 0.01M NaOH solution will have a pH of 12 .

What is the pH of 0.02 m NaOH?

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.

How do you calculate the pH of NaOH?

To calculate pH, apply the formula pOH = -log[OH-]. Work out -log[0.1] = 1. Next, apply the formula pH + pOH = 14. To isolate the pH, work out 14 – 1 = 13. The pH of your NaOH solution is 13.

How to calculate the pH of NaOH?

Calculate pOH. pOH = -log ( 0.1) Let’s solve example 1 according to method 2.

  • [H 3 O]+(aq)*[OH]-(aq) = K w
  • pH = -log 10[H 3 O+(aq)]Here,we are given the pH value. We have to calculate the concentration of KOH.

    • What is the pH level of NaOH?

    The pH of NaOH is 14. NaOH, or sodium hydroxide, is a highly caustic substance and is an alkali , or base. Sodium hydroxide is a white solid at room temperature.

    What is the molarity of NaOH?
