Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
When a solution of sulfuric acid is added to a solution of ammonium hydroxide, a neutralization reaction occurs. The sulfuric acid will donate protons to the ammonium hydroxide, forming water and ammonium sulfate salt. Heat may also be produced in the process.
One way to distinguish between sodium hydroxide and ammonium hydroxide solutions is to use a specific indicator solution such as red litmus paper. When sodium hydroxide solution is added to red litmus paper, it will turn blue, indicating it is a base. Ammonium hydroxide solution, on the other hand, does not affect red litmus paper, indicating that it is a weak base.
What is the evidence for a shift in equilibrium's when ammonium chloride was added to the stock solution in hydroxide phenolphthalein? In: http://wiki.answers.com/Q/FAQ/2455 [Edit categories]
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
When a solution of sulfuric acid is added to a solution of ammonium hydroxide, a neutralization reaction occurs. The sulfuric acid will donate protons to the ammonium hydroxide, forming water and ammonium sulfate salt. Heat may also be produced in the process.
When ammonium sulfate is added to a potassium hydroxide solution, a double displacement reaction occurs. Ammonium hydroxide and potassium sulfate are formed as products. Ammonium hydroxide is a weak base while potassium hydroxide is a strong base.
One way to distinguish between sodium hydroxide and ammonium hydroxide solutions is to use a specific indicator solution such as red litmus paper. When sodium hydroxide solution is added to red litmus paper, it will turn blue, indicating it is a base. Ammonium hydroxide solution, on the other hand, does not affect red litmus paper, indicating that it is a weak base.
When ammonium sulfate is added to a hydroxide solution, such as sodium hydroxide, it will undergo a double displacement reaction. Ammonium sulfate will react with the hydroxide ion to form ammonia gas and water, along with the corresponding sulfate compound. This reaction is exothermic and can release heat.
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
The color is pink with phenolphthalein.
