Download Solution PDFC2H2O4⋅2H2O में ऑक्सैलिक अम्ल का तुल्यांकी भार 63 है।
- ऑक्सैलिक अम्ल (C2H204) का अणुभार 90 है।
- लेकिन चूंकि ऑक्सैलिक अम्ल पानी के 2 अणुओं के साथ मौजूद है, इसलिए ऑक्सैलिक अम्ल का आणविक भार (C2H2O4⋅2H2O) = 126
- अब, तुल्यांकी भार = अणु भार/क्षारकता
- अतः, तुल्यांकी भार = 126/2 = 63 (चूंकि 2 क्षारकता है)
- यहां क्षारकता का अर्थ है ऑक्सैलिक अम्ल का 2 H+ आयन निर्मुक्त करना।
