The reaction between an acid and a base to form salt and water is called:
A. Sublimation
B. Oxidation
C. Neutralization
D. Precipitation
Answer: Option C
Solution (By JKSSB Mock Tests)
Neutralization is a chemical reaction in which an acid and a base react quantitatively with each other to form a salt and water. For example, HCl + NaOH → NaCl + H₂O. It is generally an exothermic process, and the resulting solution has a pH closer to 7.
Explanation:
Ostwald process: ammonia is oxidized with air over Pt-Rh catalyst to NO, then NO₂, then absorbed in water to give HNO₃. Haber for NH₃, Contact for H₂SO₄, Bayer for alumina from bauxite.
Explanation:
Elements in the same vertical column (group) have the same number of electrons in their outermost shell (valence electrons). This gives them similar chemical properties. The number of shells increases as we go down a group, leading to trends in atomic radius and ionization energy.
Explanation:
John Dalton formulated the law of multiple proportions: If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other are in ratios of small whole numbers. Lavoisier gave law of conservation of mass. Proust gave law of definite proportions. Dalton's atomic theory explained these laws.
