How do you prepare 0.1 m NaOH?
To prepare a 0.1M NaOH solution. -
- Dilute a standardised 1.0 M NaOH solution by a factor of 10.
- or, Dilute a non standardised 1.0 M NaOH solution by a factor of 10 and then standardise.
- or, dissolve 4 gm NaOH in 1 L of distilled water (a less accurate option also requiring standardisation)
We assume you are converting between moles NaOH and gram. This compound is also known as Sodium Hydroxide. 1 mole is equal to 1 moles NaOH, or 39.99711 grams.
- Worked example 1
- Step 1: Convert volumes to dm3 25 cm3 of HCl = 25 ÷ 1000 = 0.025 dm3
- Step 2: Determine the number of moles of sodium hydroxide. moles of NaOH = concentration × volume.
- Step 3: Work out the number of moles of acid using the balanced equation.
- Step 4: Calculate the concentration of the acid.
- Start with the number of grams of each element, given in the problem. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number.
- In analytical chemistry, a standard solution is a solution containing an accurately known concentration of an element or a substance, A known weight of solute is dissolved to make a specific volume. Standard solutions are used to determine the concentrations of other substances, such as solutions in titration.
