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.
The substance is likely a base, as bases typically lead to an increase in pH when added to a solution. Bases are substances that can accept protons or release hydroxide ions, causing the solution to become more basic.
Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
A solution with a pH of 13 is considered to be highly basic. This means that it has a low concentration of hydrogen ions and a high concentration of hydroxide ions. To lower the pH of this solution, an acid would need to be added.
If Ag+ is added to a dilute solution containing FeCl4-, a white precipitate of AgCl would form. This is because Ag+ ions react with Cl- ions to form AgCl, causing the color of the solution to change from the original color of the FeCl4- solution to white due to the formation of the precipitate.
Universal indicator added to a toothpaste solution would likely turn a shade of blue or purple, indicating that the solution is basic due to the presence of substances like fluoride or calcium carbonate found in toothpaste.
Phenolphthalein would turn pink when added to Drano, which is a strong alkaline substance. This color change indicates that the solution has become basic.
Phenolphthalein will turn pink or magenta in basic solutions and remain colorless in acidic solutions. Therefore, if added to an ammonia-based solution of window cleaner, which is basic, we would expect the solution to turn pink or magenta.
Phenolphthalein would turn pink in a borax solution, indicating the solution is basic. Borax acts as a weak base in solution and would cause phenolphthalein to change color due to its alkaline nature.
In a buffered solution, the added acid would likely be neutralized by the buffer system before causing a significant change in pH. The buffer components would absorb the excess H+ ions, helping to maintain the solution's pH relatively stable. If the amount of acid added overwhelms the buffer capacity, the pH of the solution may shift more significantly.
This would be a basic solution.
