35.5 grams of chlorine are equivalent to 127 grams of iodine; 35.5 and 127 are the equivalent weights of chlorine and iodine respectively. Hydrogen also has an equivalent weight equal to its atomic weight (1).
Additionally, how big is an iodine molecule? Gaseous iodine is composed of I2 molecules with an I–I bond length of 266.6 pm.
Also, what is molecular iodine?
Description: Iodine is an essential trace element. As with all other halogens , when freed from its compounds iodine forms diatomic molecules (I2). Iodine and its compounds are primarily used in medicine, photography, and dyes.
What is iodine also known as?
Also called iodide, iodine is a type of mineral that’s naturally found in the earth’s soil and ocean waters. Many salt water and plant-based foods contain iodine, and this mineral is most-widely available in iodized salt.

What is the structure of iodine?
Each molecule comprises two iodine atoms joined by a covalent bond. The molecules in solid iodine form a regular array with weak van der Waal’s forces between molecules. Each carbon atom is covalently bonded to four other carbon atoms in an extended tetrahedral arrangement.
What is the unit of molecular mass?
Molar mass is defined as the mass in grams of one mole of a substance. The units of molar mass are grams per mole, abbreviated as g/mol.

What is molecular iodine used for?
Iodine is taken by mouth to prevent and treat iodine deficiency and its consequences, including goiter and some thyroid disorders. It is also used for treating lumpy breasts (fibrocystic breast disease) and breast pain (mastalgia).
What are the properties of iodine?
Iodine is a solid diatomic non-metal that is very pungent in odor and a corrosive poison. Th density of iodine is 4.94 g/mL, which means it will sink in water. Chemical Properties: Iodine, I2 is not reactive towards with oxygen, O2, or nitrogen, N2.
What is the equivalent weight of HCl?
1) The gram-equivalent weight of HCl is one mole of HCl (1.008 + 35.453 = 36.461 g). 2) The gram-equivalent weight of H2SO4 is usually ½ mole since both hydrogens are replaceable in most reactions of sulfuric acid.
What is the equivalent weight of NaCl?
And the answer is that equivalent weight are additive quantity. This means that if the equivalent weight of Na is 23 gram and the equivalent weight of Cl is 35.5 gram. Therefore, the equivalent of NaCl will be equal to equivalent weight of Na + equivalent weight of Cl or, 23+35.5 grams.
What is equivalent weight of NaOH?
The equivalent mass of NaOH is 40 grams. It is according to the formula , Gram molecular weight divided by the ‘n’ factor.
What is equivalent weight formula?
Equivalent weight (EW) is the molar mass of a substance divided by the n number of equivalents in the substance. For acids or bases, the n number of equivalents is the number of hydroxide ions in the base (OH-1) , and the number of hydrogen ions in the acid (H+1).
