Why doesn’t the KHP concentration have to be exactly 0.100M? Explain using complete sentences.

Chemistry

Answer:

The answer is in the explanation.

Explanation:

The KHP is an acid used as standard in titrations to find concentration of bases as NaOH.

The reaction that explain this use is:

KHP + NaOH → KNaP + H2O

<em>where 1 mole of KHP reacts per mole of NaOH</em>

That means, at equivalence point of a titration in which titrant is NaOH, the moles of KHP = Moles of NaOH added

With the moles of KHP = Moles of NaOH and the volume used by titrant we can find the molar concentration of NaOH.

The moles of KHP are obtained from the volume and the concentration as follows:

Volume(L)*Concentration (Molarity,M) = moles of KHP

If the concentration is more or less than 0.100M, the moles will be higher or lower. For that reason, we need to know the concentration of KHP but is not necessary to be 0.100M.

PLEASE HELP <br> describe the process of paper chromatography????????????
irinina [24]

Answer:Chromatography technique that uses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass is called paper chromatography. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper.

You're welcome :)

Key terms: Reset Stereoisomers that are not mirror images of each are ____________ . The chemical and physical properties of two
sergejj [24]

Answer:

Enantiomers/ Isomers/ Stereoisomers/ Meso compounds/ Constitutional isomers/ Diastereomers.

Explanation:

Isomers are molecules that have the same chemical formula but have different conformation, or in its connections, or the orientation in space. Isomers have different chemical and physical properties (second blank).

The isomers that only differ by the orientation of their atoms in space are called stereoisomers (third blank).

The stereoisomers that have a chiral carbon and do not mirror images of each are called enantiomers (first blank). They can deviate the polarized light.

When a compound has two or more chiral carbons but they compensate for the deviation of the light, and the compound is optically inactive, it's called a meso compound (fourth blank).

When the isomers differ in the way the atoms are connected it's called a constitutional isomer (fifth blank).

When the molecule has more than one chiral carbon, it will have pairs of enantiomers. The isomers that aren't of the same pair are nonsuperimposable mirror images of each other and are called diastereomers (last blank).

Find ionic compounds ​
ella [17]

Answer:

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

  • This is because metal cationic atom has two valence electrons.
  • Non-metal anionic oxygen has six valence electrons
  • Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
  • Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
  • So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.
