<em>[H⁺] = 1,7×10⁻⁹  mol/dm³</em>

pH = -log[H⁺]
pH = -log[<span>1,7×10⁻⁹]
<u>pH = 8,77</u>

pH + pOH = 14
pOH = 14-8,77
<u>pOH = 5,23

</u>:)

Answer : The pOH of the solution is, 5.24

Solution : Given,

Concentration of H^ = 1.7\times 10^{-9}M

As we know that the pH is the negative logarithm of the hydrogen ion concentration.

First we have to calculate the pH of the solution.

pH=-\log [H^+]

pH=-\log (1.7\times 10^{-9})=8.76

Now we have to calculate the pOH.

pH+pOH=14

8.76+pOH=14

pOH=5.24

Therefore, the pOH of the solution is, 5.24

13. Which statement best describes an element? *
Natasha2012 [34]

Explanation:

Distinguish chemical substances from mixtures

Key Points

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components.

A chemical substance is composed of one type of atom or molecule.

A mixture is composed of different types of atoms or molecules that are not chemically bonded.

A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.

A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.

Various separation techniques exist in order to separate matter, including include distillation, filtration, evaporation and chromatography. Matter can be in the same phase or in two different phases for this separation to take place.

Terms

substanceA form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom or molecule.

elementA chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.

mixtureSomething that consists of diverse, non-bonded elements or molecules.

Why are alkali metals so reactive?
Savatey [412]

Answer:

<em>Alkali metals are among the most reactive metals. This is due in <u>part to their larger atomic radii and low ionization energies.</u> They tend to donate their electrons in reactions and have an oxidation state of +1. ... All these characteristics can be attributed to these elements' large atomic radii and weak metallic bonding.</em>
