What is an acid and what is a base

2 answers:

5 0

Answer: The current common definition of an acid and a base is based upon how the substance releases or attracts hydrogen ions (H+). Acids release H+ ions that can turn neutral molecules into positively charged ions, while bases can attract H+ ions from neutral molecules to produce negatively charged ions.

Answer:

An acid is usually a corrosive liquid. The pH value of acids ranges from 1-6 (7 = a neutral). Acids neutralize alkalis, dissolve some metals, and turns litmus (a water soluble mixture used to test materials for acidity) red. Acid donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bond.

A base donates electrons, accepts protons from acids, or releases hydroxide ions in liquids. The pH value of bases ranges from 8-14. Base is any substance that is slippery to the touch in water, tastes bitter, turns red litmus paper blue, and reacts with acids to form salts, and stimulates certain chemical reactions (base catalysis).

Must all four hydrogen atoms lie in the same plane? If not, what is the spatial relationship among them? Why?

RoseWind [281]

Answer:

We are considering an Allene molecule here, CH2CCH2. To answer your question, NO, they don't have to lie on the same plane. The spatial arrangement between them is that the center carbon that forms these pi bind in the left and right are PERPENDICULAR to each other.

Explanation:

We see here that The terminal carbons are sp2 hybridized, and form three σ-bonds each which means that each terminal carbon has one unhybridized p-orbital. The central carbon atom is sp hybridized, and forms two σ-bonds which means it has two unhybridized p-orbitals. For better understanding, let's call these two orbitals px and py. Summarily, These orbitals are perpendicular to each other

You have an unknownthat contains only one cation (it is oneof the twelve from this experiment).Your solution is colorless and od

algol [13]

Answer:

Your cation is Pb2+

Explanation:

This is the explanation by chemical reactions

HCl (l) ----> H+(aq) + Cl-(aq)

Pb2+(aq) + 2Cl-(aq) ---> PbCl2 (s) ↓

H2SO4 (l) ----> 2H+ (aq) + SO4-2(aq)

Pb2+(aq) + SO4-2(aq) ---> PbSO4 (s) ↓

NaOH (l) ---> Na+(aq) + OH-(aq)

Pb2+(aq) + 2OH-(aq) ---> Pb(OH)2 (s) ↓

If the reaction takes place in a strong alkaline medium, lead hydroxide dissolves in excess of base

Katarina [22]

Answer:

(S)-3-methoxy-3-methylbutan-2-ol

Explanation:

In this case, we have an epoxide opening in acid medium. The first step then is the protonation of the oxygen. Then the epoxide is broken to generate the most stable carbocation. The nucleophile ( $CH_3OH$ ) will attack the carbocation generating a new bond. Finally, the oxygen is deprotonated to obtain an ether functional group and we will obtain the molecule (S)-3-methoxy-3-methylbutan-2-ol.

See figure 1

I hope it helps!
