Answer:

0.209M

Explanation:

M1V1=M2V2

(28.5 mL)(0.183M)=(25.0mL)(M)

M2= 0.209M

Given the balanced equation:
Marta_Voda [28]
The answer is (2) A bond is formed and energy is released. The left side of equation is I atom and the right side of equation is I2 molecule. So the bond is formed between I atom to form I2 molecule. And forming bond will release energy while breaking bond will absorb energy.

\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
