Physical properties of salt in Hindi

1) A salt is a compound, formed when acid react with base.

HCl + NaoH = Nacl( salt) + H2

2) A salt is compound, formed from an acid by the replacement of the hydrogen in the acid by metal.

Zn + H2SO4 = ZnSO4 + H2O

(Zinc (Sulphuric (Zinc (Water)

metal) Acid) Sulphate salt)

3) Examples of salt :- Nacl ( common salt), Cacl2 ( calcium chloride, MgSo4 ( Magnesium sulphate)

4) Salt solution conduct electricity.

5) Many salt solution are neutral having a PH value of 7 but some salt are produce acidic or basic solution when dissolved in water.

LAWS OF CHEMICAL COMBINATIONS

LAWS OF CHEMICAL COMBINATIONS The combination of elements to form compounds is governed by the following five basic laws. 1) Law of Conservation of Mass It states that matter can neither be created nor destroyed.This law was put forth by Antoine Lavoisier in 1789. He performed careful experimental studies for combustion reactions for reaching to the above conclusion. This law formed the basis for several later developments in. chemistry Infact, this was the result of exact measurement of masses of reactants and products, and carefully planned experiments performed by Lavoisier . 2)Law of Definite Proportions This law was given by, a French chemist, Joseph Proust. He stated that a given compound always contains exactly the same proportion of elements by weight. Proust worked with two samples of cupric carbonate— one of which was of natural origin and the other was synthetic one. He found that the composition of elements presen...

PROPERTIES OF MATTER AND THEIR MEASUREMENT

PROPERTIES OF MATTER & THEIR MEASUREMENT Properties of matter & their measurement are divided in Physical and chemical properties . Every substance has unique or characteristic properties. These properties can be classified into two categories — physical properties , such as colour, odour, melting point, boiling point, density, etc., and chemical properties , like composition, combustibility, ractivity with acids and bases, etc. Physical properties can be measured or observed without changing the identity or the composition of the substance. The measurement or observation of chemical properties requires a chemical change to occur. Measurement of physical properties does not require occurance of a chemical change. The examples of chemical properties are characteristic reactions of different substances; these include acidity or basicity, combustibility, etc. 1) Mea...

molality definition and formula

Molality Formula It is characterized as the quantity of moles of solute present in 1 kg of solvent & is denoted by m. When we are estimating the physical parameter of an answer, what would it be a good idea for us to do? For certain reason, the use of molality to be sure is the most regular decision. Be that as it may, when we need to know the solute fixation in a circumstance where there's a changing in temperature, molality won't work. This is on the grounds that the arrangement's volume will change somewhat alongside the temperature, that changes ends up having a slight impact to give a mistake that should be precise. Another parameter's required, something that isn't influenced by the temperature. Molality = moles of solute(moles) Mass of solvent(Kg) Molality Formula Questions: 1) What is the molality of a...
