What is the pH of 0.010 m NaOH?

about 12The pH of 0.010 M NaOH is about 12.

How do you make a 20% NaOH solution?

20% NaOH (W/V), means 20 grams of NaOH solids, dissolved in distilled water until you have 100mL of aqueous solution. Do this in beaker slowly, and drip water until it reaches exactly 100 mL mark. 20% NaOH(W/W) means 20 grams of NaOH solids plus 80 grams of distilled water, making up 100 grams of solution.

How do you make 0.02 m NaOH?

0.02N Sodium hydroxide (NaOH): Dissolve 0.08 gm of sodium hydroxide in 100ml of distilled water taken in a volumetric flask. Phenolphthalein indicator: Dissolve 0.5gm phenolphthalein in 50ml of 95% methanol. To it add 50ml of distilled water.

What is the pH of 1 M HCl?

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).

Is NaOH a base or acid?

NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion.

How do you make 0.01 N NaOH?

To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume 1 liter. For a 0.1 N solution (used for wine analysis) 4.00 g of NaOH per liter is needed.

What is the pH of nh3?

about 11pH of Ammonia One molecule of ammonia consists of one negatively-charged nitrogen ion and three positively-charged hydrogen ions, giving ammonia a chemical formula of NH3. The pH of standard ammonia is about 11.

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.

How do you calculate the pH of HCl?

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. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.

What is the pH of 0.1 m NaOH?

13NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. Therefore pH of 0.1 M NAOH solution is 13.

What is 0.5 N NaOH?

NaOH has a valence of 1, so molar and Normal are the same. One mole of NaOH in one Liter of pure water = 1 N. Since you want 0.5, use 1/2 mole (20.0 grams) of NaOH. … M means Gram Molecular Weight, so 0.5 M means half the gram molecular weight of the chemical. In the case of NaOH the mole.

What is the pH of a 0.04 M NaOH?

1 Answer. The pH is about 12.7.
