Li + e- ===> Li+
it looses its valence electron to form a uni-positive ion
Mariulka [41]2 years ago
5 0

<u>Answer:</u> The equation for this is given below.

<u>Explanation:</u>

Lithium is the 3rd element of the periodic table having electronic configuration of 1s^22s^1

This element will loose 1 electron to attain stable electronic configuration.

Oxidation reaction is defined as the reaction in which an atom looses its electron to form a positive ion.

The chemical equation for the formation of lithium ion from lithium atom follows:

Li\rightarrow Li^++e^-

Hence, lithium ion will form lithium cation by loosing 1 electron as shown in above equation.

Which of the following salts will be less soluble in 0.10 M NaCl than it is in pure water?
MariettaO [177]

The less soluble salt : PbCl₂

<h3>Further explanation</h3>

Given

0.1 M NaCl

Required

The less soluble salt

Solution

If we see from the answer option, the salt that is more difficult to dissolve in NaCl is PbCl₂ because it has the same ion (Cl)

When PbCl₂ is dissolved in water, ionization will occur

PbCl₂ ⇒ Pb²⁺+ 2Cl⁻

So, when dissolved in NaCl, NaCl itself will be ionized

NaCl ⇒ Na⁺ + Cl⁻

Based on the principle of equilibrium, the addition of an ion (one of the ions is enlarged), the reaction will shift towards the ion that was not added. In addition to this Cl ion, the reaction will shift to the left so that the solubility of PbCl₂ will decrease (the reaction to the right decreases)
