Orthoboric acid is 2.6% soluble in water at 40°C and _ at 107 degree centigrade
Correct answer: B. 37%
- A. 26%
- B. 37%
- C. 27%
- D. < 2.6%
Explanation
Orthoboric acid's solubility in water varies with temperature. At 40°C, it's given as 2.6%. Let's see how it changes at 107°C based on typical trends:The solubility of orthoboric acid generally increases with temperature. Hence, it's safe to assume that at 107°C, the solubility of orthoboric acid would be higher than at 40°C.( 37%This option seems to align with the usual trend of increased solubility of orthoboric acid as the temperature rises.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
