Question

Aqueous solution of which of the following salts turns the red litmus blue-Na-2-CO-3-NaHCO-3-NaCO-3-10H-2-OAll of these

Toppr Admin · Accepted Answer

Na2CO3-NaHCO3-Na2CO3-x22C5-10H2O are basic in nature as H2CO3 is a weak acid and NaOH is a strong base-NaOH-H2CO3-x21CC-NaHCO3-Basic-H2ONaHCO3-H2CO3-x21CC-Na2CO3-Basic-H2O

Aqueous solution of which of the following salts turns the red litmus blue?Na2CO3NaHCO3NaCO3.10H2OAll of these

Na2CO3,NaHCO3,Na2CO3⋅10H2O are basic in nature as H2CO3 is a weak acid and NaOH is a strong base.NaOH+H2CO3⇌NaHCO3(Basic)+H2ONaHCO3+H2CO3⇌Na2CO3(Basic)+H2O

Aqueous solution of which of the following salts turns the red litmus blue?
$N a_{2} C O_{3}$
$N a H C O_{3}$
$N a C O_{3} .10 H_{2} O$
All of these

$N a_{2} C O_{3}, N a H C O_{3}, N a_{2} C O_{3} \cdot 10 H_{2} O$ are basic in nature as $H_{2} C O_{3}$ is a weak acid and $N a O H$ is a strong base.
$N a O H + H_{2} C O_{3} ⇌ N a H C O_{3} (B a s i c) + H_{2} O$
$N a H C O_{3} + H_{2} C O_{3} ⇌ N a_{2} C O_{3} (B a s i c) + H_{2} O$
