\bold{\huge{\underline{ Solution }}}

<h3><u>Basic </u><u>Characteristic </u><u>of </u><u>acids </u></h3>

  • Acids are sour in taste
  • Acid turns blue litmus paper or solution into red litmus paper or solution
  • Acids are good conductor of electricity because it dissociate into cation in aqueous solution
  • Acids classified into edible acids and non edible acids. Non edible acids are very hazardous
  • Generally, All acids are soluble in water
  • Acids have PH smaller than 7

<u>Arrhenius </u><u>definition </u><u>of </u><u>acids </u><u>:</u><u>-</u>

According to Arrehinus,

  • Acids are those substances which when dissolve in water given H positive ions . Then, this hydrogen ions combine with water to form H30 + ions

<u>Second </u><u>definition </u><u>of </u><u>Acids </u><u>was </u><u>given </u><u>by </u><u>Bonsted </u><u>Lowry </u><u>:</u><u>-</u>

According to Bonsted Lowry

  • Acids are the proton donors that is when acids dissociate into water gives hydrogen ions that is H+ ions

<u>3rd </u><u>definition </u><u>was </u><u>given </u><u>by </u><u>Lewis </u>

According to Lewis

  • Acids are those substances which have the ability to accept a pair of electrons .

Example of Acids

  • HNO3 :- Nitric acid
  • H2SO4 :- Sulfuric acid
  • HCl :- Hydrochloric acid

<h3><u>Basic </u><u>characterists </u><u>of </u><u>bases </u></h3>

  • Bases are bitter in taste
  • Bases turns red litmus paper into blue litmus paper or solution
  • Bases are also good conductor of electricity because on dissociation it produces anion in aqueous solution
  • Bases are also good conductor of electricity
  • When bases are soluble in water then they are known as alkaline base
  • Bases have PH greater than 7

<u>Arrehinus definition of bases :-</u>

According to Arrehinus ,

  • Bases are those substances which when dissolve in water produce OH negative ions that is hydroxide ions

<u>Bonsted Lowry definition </u>

According to Bonsted Lowry

  • Bases are the proton donors as they produce OH negative ions in dissociation in aqueous solution

<u>Lewis </u><u>definition </u>

According to Lewis

  • Acids are those substances which have the ability to lose electrons that is they are electron donors.

Example of bases

  • Ca(OH)2 :- Calcium hydroxide
  • NaOH :- Sodium hydroxide
  • KOH :- Potassium hydroxide

[ Note :- There are so many Lewis acids and bases but they are not Arrhenius or Lowry acids or bases ]

<h3><u>Basic </u><u>characteristic </u><u>of </u><u>salt </u></h3>

  • Salts are the ionic compounds which are composed of acids and bases that cation and anion
  • Salts are generally found in oceans and seas in the forms of crystals
  • As they are composed of acids and bases so they are neutral in nature but the salt of strong acid or weak base is acidic in nature or vice versa
  • Salts are also good conductor of electricity as they form ionic bond
  • Generally, All salts are soluble in water.
  • The PH of common Salt is 7

Example of salts

  • NH4Cl :- Ammonium chloride
  • CuSO4 :- Copper sulphate
  • NaCl :- Sodium chloride

Use the helium-4 isotope to define atomic number and mass number. why does knowledge of atomic number enable us to deduce the nu
Nuetrik [128]
Helium - 4 isotope has 2 protons and 2 neutrons.

Its atomic number is 2 (the number of protons). Atomic number is the number of protons in the atom of an element and it identifies the element. All the isotopes of an element have the same atomic number (same number of protons). So, all the isotopes of hellium have 2 protons.

The number 4 that identifies the helium - 4 isotope is the mass number, i.e. the number of protons plus the number of neutron. So, helium-4 isotope has 2 protons and 2 neutrons. While, other isotopes of helium have 2 protons but different number of neutrons.

The atomic number enable us to deduce the number of electrons in an atom because the atoms are neutral, which implies that the positive and negative charge are equal. Given that the magnitude of the charge of electons and protons are equal but the sign is opposed (protons are positve and electrons are negative) the number of electrons in the atom equals the number of protonts. That is why the atomic number is also the number of electrons of the atom.

Question 10 (1 point)
levacccp [35]
The empirical formula gives the relative ratio of atoms in each element. Therefore, it simplifies the whole numbers. For example C2H6 can be reduced to CH3 because they share the greatest common factor (2). The answer to this question would be #1. C4H10 can be reduced to C2H5 because 4 and 10 are both divisible by 2. C2H5 can not be reduced any further. All of the other options do not have a greatest common factor making them a empirical formula.
