Which is the weakest reducing agent?

Which is the weakest reducing agent?

Hydrogen

Which substance is a reducing agent?

A reducing agent is oxidized, because it loses electrons in the redox reaction. Examples of reducing agents include the earth metals, formic acid, and sulfite compounds. Figure 1: A reducing agent reduces other substances and loses electrons; therefore, its oxidation state increases.

Is KMnO4 a reducing agent?

The oxalic acid acts as a reducing agent, and the KMnO4 acts as an oxidizing agent, KMnO4 acts as an indicator of where the permanganate ions are a deep purple colour.

Is KMnO4 a catalyst?

KMnO4 chemical can exert excellent catalytic effect and increase the porosity in cement slurry foamed by H2O2. The higher porosity, the lower thermal conductivity.

What Colour is KMnO4?

purplish

Is KMnO4 a salt?

Potassium permanganate is a salt of permanganic acid.It neither acid nor base. It is neutral. Its a salt as the K + ions are from KOH which is a strong base and MnO4 ions from HMnO4 which is an acid .

Is KMnO4 a pure compound?

Answer. Answer: Potassium permanganate, also known as permanganate of potash or Condy’s crystals, is a chemical compound with a chemical formula of KMnO4, made of a potassium (K+) ion and a permanganate (MnO4-) ion. It is a strong oxidizing agent, so it readily takes or accepts electrons from other substances.

Is KMnO4 a acid?

Potassium permanganate is a strong oxidizing agent in acid medium, but is a weak oxidant in the neutral and alkaline medium.

What is the equivalent weight of feso4?

So, the molecular weight of ferrous sulphate is 151.8. -Equivalent weight of ferrous sulphate = molecular weight of ferrous sulphate/ involved electron. So, equivalent weight of ferrous sulphate which is present as reductant is 151.8 which is equal to the molecular weight of ferrous sulphate.

What is the N factor of FeSO4?

n factor is defined for compounds involved in redox reactions as Numberif moles of electrons lost or gained by one mole of the given substance. In the above reaction, Fe+2 is changing to Fe+3. So only one electron is involved. n factor of FeSO4 = 1.

What is equivalent weight of oxygen?

Hydrogen has atomic weight 1.008 (rounded to three decimal places) and always assumes valence 1 in compounds, so its equivalent weight is 1.008. Oxygen has an atomic weight of 15.999 and always assumes valence 2 in compounds, so its equivalent weight is 7.9995.

How is equivalent weight calculated?

The concept of equivalent weight has been displaced by that of molar mass, which is the mass of one mole of a substance. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).

What is normal solution in chemistry?

A solution made by dissolving 1 g-equivalent weight of a substance in sufficient distilled water to make 1 L of solution.

How do you find equivalents in chemistry?

To calculate molar equivalents for each reagent, divide the moles of that reagent by the moles of the limiting reagent: Note that the molar equivalency of sodium benzoate is 1. This is because sodium benzoate is the limiting reagent. Any reagents used in excess will have a molar equivalency greater than one.

What is the formula of normality in chemistry?

Hence, N = NumberofequivalentsVolumeinlitres = 2/1 = 2 Eq/lt. Question: What is the normality of 0.1381 M NaOH? Since the Equivalent Weight of NaOH is equal to Molar Mass hence the molarity is equal to Normality in this case.

What is 1 N NaOH?

Making 1 N solution of 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.

How do we calculate normality?

Normality Formula

  1. Normality = Number of gram equivalents × [volume of solution in litres]-1
  2. Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
  3. N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
  4. N = Molarity × Molar mass × [Equivalent mass]-1
  5. N = Molarity × Basicity = Molarity × Acidity.

How do you make 1 N HCl?

If we add 8.33mL in 100 L of water we get 1 N HCl.

What is difference between normality and molarity?

One of the main differences between the normality and molarity of a solution is that normality describes the amount of gram equivalent of compound present in the solution while molarity describes the number of moles present in the solution.

How do you make 2 N HCl?

2N HCl. Prepare 1 L of 2N HCl by mixing 834 ml of deionized water and 166 ml of concentrated 12N HCl. This solution is stable at room temperature. Caution: This solution should be prepared under a hood with the HCl slowly being added to the deionized water.
