a compound p is heated in a test tube with sodium hydroxide solution. a red litmus paper held at the mouth of the test tube turns blue. which of the following could compound p be?
What could compound P be if heating it in a test tube with sodium hydroxide solution turns a red litmus paper blue?
Answer:
When a compound is heated in a test tube with sodium hydroxide solution and a red litmus paper turns blue, it indicates that the compound is basic or alkaline in nature. This reaction suggests that the compound P could be one of the following:
-
Metal hydroxide: Compounds of metals with hydroxide ions can turn red litmus blue, indicating basic behavior. Examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), or calcium hydroxide (Ca(OH)2).
-
Metal oxide: Metal oxides can react with water to form basic solutions, turning red litmus paper blue. Some metal oxides that could be compound P are sodium oxide (Na2O), potassium oxide (K2O), or magnesium oxide (MgO).
-
Ammonium compound: Ammonium compounds can also show basic properties. For instance, ammonium hydroxide (NH4OH) is a basic solution that can turn red litmus blue upon heating with sodium hydroxide.
These are some possibilities for compound P based on the given reaction with sodium hydroxide solution and red litmus paper. Further testing and analysis would be needed to confirm the exact identity of compound P.
