What do you mean by 0.5 m NaOH?

0.5 m of NaOH means that 0.5 mole (20.0 g) of NaOH are dissolved in 1000 g of the solvent. 0.5 M of NaOH means that 0.5 mole (20.0 g) of NaOH are dissolved in 1000 mL of the solution. 2:51. 1:47. 2:08.

What is 0.1 N NaOH?

So the equivalent weight of NaOH is 40. 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 0.02 m NaOH?

12.30pH of 0.02M of NaOH is 12.30.

What is 0.5m solution?

You know that “0.5 M” literally means 0.5 moles per liter. … You know that you will make 200 ml of a NaOH solution that is 0.5 M. You know that to do this, you will weigh out so many grams of NaOH and add water to dissolve it, ending up with 200 ml.

How can we prepare 0.1 N NaOH in 100 mL?

To make 0.1N NaOH solution = dissolve 40 grams of NaOH in 1L of water. For 100 ml of water = (4/1000) × 100 = 0.4 g of NaOH. Thus, the amount of NaOH required to prepare 100ml of 0.1N NaOH solution is 0.4 g of NaOH.

How many grams of NaOH are in 500mL of a 1m solution?

40 grams NaOHUnderstanding math via the real world. Everything looks good except for this part: “To make one mole NaOH solution, dissolve 40 grams NaOH in 500mL of H2O.” To make a one molar solution you want to put one mole of the solute into 1L (1000mL) of H2O. Then you can do your conversion the other way from L to mL.

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 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).

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 acidity of NaOH?

Thus, 0.00126 moles of NaOH (Step 2) would interact with 0.00063 moles of tartaric acid. Divide the number of moles of the acid (Step 4) by the aliquot volume and then multiply by 100 to calculate the acid amount in 100 ml of the solution. In our example, amount (C4H6O6)=0.00063 moles x 100 ml/15 ml=0.0042 moles.

What is the pH of a 0.05 M solution of sodium hydroxide?

1 Answer. The pH is about 12.7.
