Experimental Definitions

Earlier, acids, bases, and salts were characterized by the experimental testing of their aqueous solutions. An acid is defined as a substance whose water solution TASTES sour, turns blue litmus red and neutralizes bases. A substance is called base if its aqueous solution tastes bitter, turns red litmus blue or neutralizes acids.

Acids

Salt is a neutral substance whose aqueous solution does not affect litmus. According to Faraday: acids, bases, and salts are termed as electrolytes. Further, Liebig proposed that acids are compounds which contain hydrogen that can be replaced by metals.

Acids

Acidity is a characteristic property of acids. Acidic substances are usually very sour. Apart from hydrochloric acid, there are many other types of acids around us. Citrus fruits like lemons and oranges contain citric and ascorbic acids while tamarind paste contains TARTARIC acid.

In fact, the word ‘acid’ and ‘acidity’ are derived from the Latin word ‘acidus’ which means sour. If you dip a blue litmus paper into an acid, it will turn red while a red litmus paper will not change colour. Acids also liberate dihydrogen when they react with some metals.

Bases

Bases turn red litmus paper blue while the blue litmus paper stays blue. They taste bitter and also feel soapy. Some other common examples of bases include sodium bicarbonate that is used in cooking and household bleach.

Salts

Apart from sodium chloride, other common salts are sodium nitrate, barium sulfate etc. Sodium chloride or common salt is a product of the reaction between the hydrochloric acid (acid) and sodium hydroxide (base). Solid sodium chloride is made of a cluster of positively charged sodium ions and negatively charged chloride ions held together by electrostatic forces.

Electrostatic forces between OPPOSITE charges are inversely proportional to the dielectric constant of the medium. In other words, we can say that a compound that has acidity in its nature and a compound that has basicity as its nature, MAY yield salts when combined together.

The universal solvent, water, has a dielectric constant of 80. Therefore, when sodium chloride is dissolved in water, the dielectric constant of water reduces the electrostatic force, allowing the ions to move freely in the solution. They are also well-separated due to HYDRATION with water molecules.

The internal structure of Earth is layered in SPHERICAL shells: an OUTER silicate solid CRUST, a highly viscous asthenosphere and MANTLE, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of the internal structure of Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravitational and magnetic fields of Earth, and experiments with crystalline solids at pressures and temperatures characteristic of Earth's deep interior.

ong>Explanation:

Number of moles of organic compound is = 0.9/90 = 0.01 mol

After KOH treatment VOLUME CO2 decreased = 560-112 = 448 ML

It means the volume of CO2 produced is 448 ml

22400 ml of CO2 = 1 Mol of CO2 at stp

So 448 ml contains = 448/22400 = 0.02 mol

0.01 mol of organic compound produces 0.02 mol CO2

So 1 mol organic compound produce = 0.02/0.01 = 2 mol CO2

So number of C in the organic compound is 2

So the MOLECULAR formula C2HxOy 24+ x1 + 16 y = 90

Substitute some possible VALUES GIVES x =2 and y = 4

Hence the molecular formula is C2H2O4

C) CUTTING of SODIUM PEACE with the knife

ong>EXPLANATION:

We KNOW that,

dv⃗dt=a⃗

Multiplying and dividing LHS by ds⃗

⟹dv⃗ds⃗ds⃗dt=a⃗

We replace ds⃗dt with v⃗ to get

v⃗dv⃗ds⃗=a⃗

⟹v⃗dv=a⃗ds

We know that at S=0,V=u and at S=s,V=v ,

Integrating both sides with appropriate limits:

⟹∫vuvdv=∫s0ads

⟹v22|vu=as|s0

⟹v22−u22=a(s−0)

⟹v2−u22=as

⟹v2−u2=2as

⟹v2=u2+2as

Or more APPROPRIATELY,

v⃗⋅v⃗=u⃗⋅u⃗+2a⃗⋅s⃗
