What is the gram equivalent weight of NaOH?

40 g/mol
The equivalent weight of sodium hydroxide NaOH is 40 g/mol.

What is the pH of NaOH?

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

How do you calculate gram equivalent weight?

Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n.

What is the equivalent weight of hydroxide?

The equivalent weight of an acid or base for neutralization reactions or of any other compound that acts by double decomposition is the quantity of the compound that will furnish or react with or be equivalent to 1.008 g of hydrogen ion or 17.0074 g of hydroxide ion—e.g., hydrochloric acid (HCl), 36.461 g; sulfuric …

What is the N factor of NaOH?

For bases, n-factor is defined as the number of OH– ions replaced by 1 mole of base in a reaction. Note that n-factor is not equal to its acidity i.e. the number of moles of replaceable OH– ions present in 1 mole of base. For example, n-factor of NaOH = 1.

How do you find the pH of NaOH?

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 do you calculate the pH of NaOH?

Calculate the pH of a 0.1 M NaOH solution. Alternatively we can calculate pOH = – log [OH-]= – log [10-1] = 1 and remembering that pH + pOH = 14 we get pH = 14 – 1 = 13.

What is the formula for equivalent mass?

The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.

What is the difference between gram equivalent and equivalent weight?

The key difference between gram equivalent and equivalent weight is that gram equivalent describes that the mass of one equivalent is given in the unit of gram whereas equivalent weight describes the mass of one equivalent in any unit of measurement.

What is equivalent weight formula?

Equivalent Weight = Molecular weight/ Valency.

Which is the equivalent mass of NaOH in grams?

The equivalent mass of NaOH is 40 grams. Gram molecular weight divided by the ‘n’ factor. ’n’ factor will be 1 because in case of ionic compounds we need to take the total charge present on one type of i.e. either that of the cation or that of the anion.

How to calculate the pH of NaOH solution?

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. Did you find this page helpful?

Is the normality and molarity of NaOH the same?

Since the valence of NaOH is 1, for this compound, 1 mol = 1 eq. This means that for NaOH solutions, normality and molarity are the same, unlike the case with CaCO3.

What is the equivalence factor of NaOH for H 2 SO 4?

This equivalence factor can be thought as the number of replaceable H + ions in a molecule of an acidic solute or the number of replaceable OH – ions present in a molecule of a basic solute. Thus equivalence factor of NaOH is 1 and 2 for H 2 SO 4.
