The salt As2S3 is a negatively charged salt. According to Hardy and Schulz rule, the ions having higher positive charge value will attract more negative charged ions. Here, Mg2+ has 2 positive ions where K+ has 1 positive ion. As the charge of Mg2+ is more, it'll attract more negative charged ions; so gravitational force will work downward and will easily settle down than K+. That's why MgCl2 is a better coagulant than KCl.

Why mgcl2 is better coagulant then kcl for As2S3?
MgCl2 is a better coagulant for As2S3 because magnesium ions form stronger electrostatic bonds with the negatively charged sulfide ions in the As2S3, leading to better coagulation and precipitation of the arsenic sulfide particles. Additionally, magnesium ions have higher charge density compared to potassium ions from KCl, providing better bridging and agglomeration of the colloidal particles.
What has a greater boiling point elevation when dissolved at a concentration of 1mol in water with NaCl or MgCl2?
In the same volume of water, one mole of MgCl2 will give rise to a greater boiling point elevation. This is explained by the fact that boiling point elevation is a colligative property, that is, the relative amounts of the constituents are important and not their identity. We can determine by inspection that, upon dissociation, more ions will be produced by MgCl2 than NaCl since there are more atoms in the MgCl2 molecule. So, for one mole of MgCl2, we will produce one mole of magnesium and two of chlorine (three total). For one mole of NaCl, we produce one mole each of potassium and chlorine. By employing the principle stated above, we can come to the correct conclusion.
What has the largest formula mass LiCl NaCl KCl MgCl2.?
MgCl2 has the largest formula mass among the given compounds. This is because the formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit, and magnesium (Mg) has a greater atomic mass than lithium (Li), sodium (Na), and potassium (K).
Is 1 mole of Na Cl and 1 mole of MgCl2 has same No of ions?
NO!!! In one molecule of NaCl there are TWO(2) ions ; Na^(+) & Cl^(-) In one molecule of MgCl2 there are THREE(3) ions ; Mg^(2+) , Cl^(-) & Cl^(-) . Hence it follows that in one mole of NaCl there are less ions than there are in one mole of MgCl2, by a ratio of 2:3 .
Mgcl2 strong electrolyte?
HCl is a strong acid. MgCl2 is a salt , not an acid. NB when writing chemical formulas, remember, single letter elements are always a CAPITAL letter. e.g. Hydrogen (H). Elements with two letters are written ; first letter is a CAPITAL letter, second letter is lower (small) case, e.g. Magnesium (Mg) ; Neither 'MG' nor 'mg'

Is Li MgCl2 LiCl Mg a single replacement?
No, Li and Mg are not capable of displacing each other in a single replacement reaction because Li is less reactive than Mg. Therefore, LiCl + MgCl2 will not undergo a single replacement reaction.

Which has a higher boiling point between NaCl and MgCl2?
MgCl2 because it has more electrons (due to the Mg over Na). Because of the higher number of electrons, it has higher dispersion forces (attractive forces). This means that more energy (heat) is required to unstick the molecules into a different state of matter.NaCl, due to complex arrangement and interaction of molecules, can't be easily explained by using simple dispersion, dipole-dipole interaction.Although NaCl's higher melting point can be explained by its bonding in its crystal lattice arrangement compare to MgCl2.
Am i better than you?
You are the worst person ever. You are better than no one. And no one is better than the best. So you must be better than the best. But the best is better than the worst. So it is impossible to tell if you're better than me. No wait. I change my answer to "No, I'm better than you."

What is the meaning of I is better than me and you?
The correct wording is "You are better than I." The way to tell is to finish the sentence - "You are better than I am" is correct, whereas "You are better than me am" would be incorrect.
Why is lattice energy of MgF2 greater than MgCl2?
since ca2+ has a larger atomic radii compared to Mg2+ (and the same for F and CL2), the electrons are dispersed over a wider surface area and so have a lesser strength than that of magnesium. Hence, with a smaller atomic radii, Magnesium has stronger attractive forces with require more energy to be broken and therefore making it more exothermic than calcium.
What is the chemical equation for magnesium plus chlorine?
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.
