What is an equivalent in Chem?
What is an equivalent in Chem?
An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. …
What is equivalent concept?
An equivalent concept is “gram equivalent weight” or “gram equivalent” concept. It is based on equivalent weight. Mass of one gram equivalent, like its mole counterpart, is equal to mass in gram, which is numerically equal to equivalent weight.
What is an equivalent solution?
Systems of equations that have the same solution are called equivalent systems. Given a system of two equations, we can produce an equivalent system by replacing one equation by the sum of the two equations, or by replacing an equation by a multiple of itself.
What is an equivalent in math?
The term “equivalent” in math refers to two values, numbers or quantities which are the same.
How do you find the number of equivalents?
- Mole = given mass / molar mass …….(
- G.eq. =
- But, equivalent mass = Molar mass/x.
- Here, x can be valency for element, acidity for base and basicity for acid.
- Now, equation (ii) can be written as.
- G.eq = (given mass)/Molar mass/x.
- => G.eq = (given mass/Molar mass)x.
- But according to equation (i) given mass/Molar mass is no.
Is 1m HCL dangerous?
Strongly corrosive to body tissue and moderately toxic by ingestion. Target organs: Respiratory system, eyes, skin, lungs. This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200). Hydrochloric Acid, 37% (7647-01-0), 9-10%.
What is the normality of the following 0.1381 m NaOH?
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.
How do you make 0.2 N NaOH?
Both are based on the molecular weight of NaOH – 40g/mol. Four (4) grams is 0.1 mole NaOH, so dissolving it in one (1) liter of water will result in a 0.1M, or 0.1N solution of NaOH. A 0.2N solution would require 8.0 grams of NaOH per liter of water.
What is meant by normality?
Normality (N) is defined as the number of mole equivalents per liter of solution:normality = number of mole equivalents/1 L of solution. Like molarity, normality relates the amount of solute to the total volume of solution; however, normality is specifically used for acids and bases.
