Base turn red cabbage solution to blue-ish purple
When sodium hydroxide is added to red cabbage juice, the cabbage juice will change color. The cabbage indicator will turn from red/pink to blue/purple because sodium hydroxide is a strong base, causing a shift in the pH of the solution. This color change is due to the anthocyanin molecules in the red cabbage juice reacting with the change in acidity.
Adding base will increase pH-level
When a base is added to water, it reacts to form hydroxide ions (OH-) which increases the pH of the solution. This reaction can result in the solution becoming more basic or alkaline.
It will turn a red color indercating that is has got acid in it
it turns greenish yellow if it is added to a base
it is a controll when a acid or a base is added it changes color
You will get a frothy red mess. The baking soda and vinegar will combine to produce carbon dioxide as the acid in the vinegar combines with the base in the baking soda. The red cabbage will will make it colorful, and the water will slow the reaction. On the other hand, red cabbage and vinegar will make a nice pickled cabbage.
When a base is added to an acid, a neutralization reaction occurs, forming water and a salt. This process helps to balance the pH level by reducing the acidity of the solution.
The acid and base will neutralize each other and the resulting solution will be more neutral. If the base being neutralized is strong, the resulting salt will be neutral. If the base is weak the resulting salt will be acidic. A solution of such a salt may be called a buffer.
When a strong base is added to water, it ionizes to release hydroxide ions (OH-) which then react with water molecules to increase the concentration of hydroxide ions in the solution. This leads to an increase in pH, making the solution more basic.
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.
Ammonia is a base, not an acid. When mixed with red cabbage indicator, it may turn the solution blue or green, indicating a basic pH.
