How are radicals applied in real life?
Radical expressions are utilized in financial industries to calculate formulas for depreciation, home inflation and interest. Electrical engineers also use radical expressions for measurements and calculations. Biologists compare animal surface areas with radical exponents for size comparisons in scientific research.
Which are the basic radicals?
State the difference between: acid radical and basic radical
| Acid radicals | Basic radicals |
|---|---|
| Acid radicals are formed by removal of hydrogen ion (H+). | Basic radicals are formed by the removal of hydroxide ion (OH–). |
| Example: H2S04 loses one H+ ion to form HSO4– ion. | Example: KOH loses OH– ion and becomes K+ ion. |
What is bivalent radical?
Answer Expert Verified In chemistry bivalent refers to an element whose atom can replace 2 atoms of hydrogen or other univalent element. It also refers to a radical that has the same valence as a bivalent atom. For example, calcium in its chlorid CaCl2 replaces 2 atoms of hydrogen in hydrochloric acid HCl.
Why cations are called basic radicals?
Cation and anion are called basic and acidic radicals, respectively, because during salt formation cation comes from base and anion comes from acid.
What is radical test?
This is a simple non-invasive urine test that will detect and measure free radical activity in the body. Excessive free radical activity can also mean that the body lacks anti-oxidants and may be considered a measure of antioxidants adequacy.
How do you identify a radical acid?
Thus, the acid radicals may be identified by performing the following tests in the order given below : (i) Dil….These gases on identification indicate the nature of the acid radical present in the salt.
- Carbonates.
- Sulphides.
- Sulphites.
- Nitrites.
Which is the second group Radical?
| Group | Basic radicals | Group reagent |
|---|---|---|
| I | Ag+,Hg2+2(I) , Pb2+ | Dil. HCl |
| II | Cu2+, Cd2+, Pb2+, Hg2+ (II), Bi3+, As3+, Sb3+, Sn2+ | H2S gas in presence of dil. HCl |
| III | Al3+, Cr3+, Fe3+ | NH4OH in presence of NH4Cl |
| IV | Zn2+, Ni2+, Mn2+, Co2+ | H2S in ammonical medium |
Which radical is MgSO4?
MgSO4 —This salt was formed from the reaction of a strong base, magnesium hydroxide, with strong acid, sulfuric acid. This reaction results in a neutral salt.
What is meant by acidic radical?
Acid radical is the ion formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical. The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical.
Why are basic radicals divided into groups?
Basic radicals (cations) have been divided into groups based on Ksp values.
How many basic radical groups are there?
| Group | Basic radicals | Ppt. as |
|---|---|---|
| II | Cu2+, Cd2+, Pb2+, Hg2+ (II), Bi3+, As3+, Sb3+, Sn2+ | Sulphides (CuS, CdS, PbS, HgS, Bi2S3, As2S3,Sb2S3,SnS) |
| III | Al3+, Cr3+, Fe3+ | Hydroxide Al(OH)3, Cr(OH)3, Fe(OH)3 |
| IV | Zn2+, Ni2+, Mn2+, Co2+ | Sulphides (ZnS, MnS, NiS, CoS) |
| V | Ca2+, Ba2+, Sr2+ | Carbonates (CaCO3, BaCO3, SrCO3) |
What are the basic radicals belongs to Group IIIA?
In group III, the basic radicals are iron, aluminium and chromium and are precipitated as their hydroxides.
What is meant by group reagent?
The “Group reagent” is a cocktail of reagents that serves as a prima facie indication of a particular cation, characterized by the formation of a precipitate during a positive test/result and no precipitation in the event of a negative test/result.
Which one of the following cation is not present in group II?
Thus, chromium ion is not included in 2nd group, it is included in third analytical group of cation as Cr+3. Was this answer helpful?
Why is ammonia in zero group?
Also, the compound of ammonium have very high solubility product. Therefore, they are given special attention, and a place in group zero.
Why is ammonium ion considered a member of Group V?
(I), Ammonium (I) The salts of the cations of group V, with few exceptions, are quite soluble, this accounts for the fact that there is no common precipitating reagent for the group. – This group is called “Soluble Group” because its cations remain soluble throughout the whole scheme of separation.
Is ammonium ion a basic radical?
In ammonium cation, there are SIX electrons associated with nitrogen, rather than the 7 required for neutrality. The nitrogen in ammonia is (so-called) quaternized, and thus bears a positive charge.
What is a zero group?
: the group of inert gases having a valence of zero in the periodic table.
What is another name for Group 0?
The elements in group 0 are called the noble gases . They exist as single atoms .
What are the first group elements?
Alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Who introduced the zero group?
William Ramsay
What are Group A elements called?
The elements in group IA are called the alkali metals.
What is the group reagent of zero group?
Salt Analysis of Cations and Anions
| Group | Group Reagent | Radicals |
|---|---|---|
| Zero Group | O.S. + NaOH + Heat | NH4+ |
| I Group | O.S. + HCl | Pb2+ |
| II Group | O.S. + HCI + H2S | Cu2+ |
| III Group | O.S. +NH4Cl + NH4OH | AI2+ ,Fe3+ |
Are zero group elements and 8th group elements are same?
Yes, zero group elements and 8th group elements are the same. The 8th A group is also called the noble gas family or the zero group. It is called a zero group since all the elements except Xenon are non-reactive and have zero valency or zero electrons possible for splitting. Was this answer helpful?
