Answer: Option (A) is the correct answer.

Explanation:

When a neutral atom loses an electron then it acquires a negative charge and if a neutral atom gains an electron then it acquires a positive charge. Hence, an ion is formed in both the cases.

For example, sodium on losing an electron become $Na^{+}$ ion.

An isotope is defined as the specie which contains same number of protons but different number of neutrons.

For example, $^{14}_{7}N$ and $^{15}_{7}N$ are isotopes.

A molecule is defined as a substance that contains chemically combined two or more number of atoms of an element.

For example, $Cl_{2}$ is a molecule.

Whereas a compound is defined as a substance in which different atoms of different elements chemically combine together in a fixed ratio by mass.

For example, $H_{2}O$ is a compound.

Thus, we can conclude that an ion is an electrically charged atom.

A saturated solution of Pb(IO3)2 in pure water has a lead ion concentration of 5.0 x 10-5 Molar. What is the Ksp value of Pb(IO3

Orlov [11]

Answer:

Option (E) is correct

Explanation:

Solubility equilibrium of $Pb(IO_{3})_{2}$ is given as follows-

$Pb(IO_{3})_{2}\rightleftharpoons Pb^{2+}+2IO_{3}^{-}$

Hence, if solubility of $Pb(IO_{3})_{2}$ is S (M) then-

$[Pb^{2+}]=S(M)$ and $[IO_{3}^{-}]=2S(M)$

Where species under third bracket represent equilibrium concentrations

So, solubility product of $Pb(IO_{3})_{2}$ , $K_{sp}=[Pb^{2+}][IO_{3}^{-}]^{2}$

Here, $[Pb^{2+}]=S(M)=5.0\times 10^{-5}M$

So, $[IO_{3}^{-}]=2S(M)=(2\times 5.0\times 10^{-5})M=1.0\times 10^{-4}M$

So, $K_{sp}=(5.0\times 10^{-5})\times (1.0\times 10^{-4})^{2}=5.0\times 10^{-13}$

Hence option (E) is correct

The total concentration of ions in a 0.75 M solution of HCl is

EastWind [94]

<h3>Answer:</h3>

The total concentration of ions in a 0.75 M solution of HCl is 1.5 M

That is; 0.75 M H⁺ and 0.75 M Cl⁻

<h3>Explanation:</h3>

Concentration or molarity is the number of moles of a compound or an ion contained in one liter of solution. It is measured in moles per liter (M).
The concentration of ions making a compound is determined by the ratio of moles of the compound and the constituents ions.

For instance, HCl dissociates to give H⁺ and Cl⁻

HCl(aq) → H⁺(aq) + Cl⁻(aq)

Therefore, since the mole ratio between HCl and the constituent ions H⁺ and Cl⁻ is 1:1, then 0.75 M of HCl dissociates to give 0.75 M H⁺ and 0.75 m Cl⁻

Hence the total concentration of ions in a 0.75 M solution of HCl is 1.5 M (0.75 M H⁺ and 0.75 M Cl⁻)
