Tardigrade Admin · Accepted Answer

For a compound to give positive NaHCO 3 test it must be more acidic than H 2 CO 3( pKa =6.4) And for a compound to give positive NaOH test, it must be more acidic than H 2 O ( pKa =15.7) <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/f0d54b44780df6cdf11897ca0cef3dc3-.png" />

Q. Which of the following compounds is differentiated by $N a H C O_{3}$ as well as by $N a O H$ ?

For a compound to give positive $N a H C O_{3}$ test it must be more acidic than $H_{2} C O_{3} (p K a = 6.4)$ And for a compound to give positive $N a O H$ test, it must be more acidic than $H_{2} O (p K a = 15.7)$
