Why is potassium chloride is soluble in water?

Chemistry
1 answer:
Lelu [443]4 years ago
6 0
It happens because of the bonding in the two compounds. Potassium chloride is an ionic compound, meaning it has polar bonds which, in water, causes it to be dissolved, as the stronger polar bonds in water pull them apart. Potassium has metallic bonding, so it can't be pulled apart by the water. Instead they react (explanation for this is long, so I advise looking it up if you need more in-depth information). Basically it's the difference in bonds that makes potassium chloride soluble. (Not in my own words,I found this)

Answer:

B) Polonium and Arsenic

Explanation:

Metalloids are a small category of elements that are right between metals and non-metals, and have properties from those categories.

The most recognized are: Boron, Silicon, Germanium, Arsenic,  Antimony, and Tellurium.

Some that are irregularly recognized are Polonium and Astatine.

The only option with the elements in either of the shown elements is B) Polonium and Arsenic.

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 molar mass of h2o is 18.01 g/mom . The molar mass of o2 is 32.00 g/moo .what mass of h2o on grams must react to produce 50.0
Julli [10]
Oxygen can be obtained from water using electrolysis process as follows:
2 H2O .............> 2H2 + O2

It is given that: 
molar mass of water = 10.01 grams and molar mass of O2 = 32 grams

From the balanced chemical equation, we can conclude that:
2 moles of water produce 1 mole of oxygen
2 x 18.01 = 36.02 grams of water produce 32 grams of oxygen.

To calculate how many grams of water must react to produce 50 grams of oxygen, we can use cross multiplication as follows:
mass of required water = 56.28125 grams
