since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
Alkalis turn universal indicator blue or purple in color.
In lime water, which is basic, universal indicator will turn purple or blue to indicate the presence of high pH.
The color indicator in sugar water can vary depending on the type of indicator used. Common indicators like phenolphthalein can turn pink or red in basic solutions, while litmus paper can turn blue in basic solutions and red in acidic solutions. It is important to choose the appropriate indicator based on the pH level you are testing for in the sugar water.
The color of a universal indicator in a basic solution is usually purple or blue.
No, universal indicator does not turn red when diluted in water. Instead, it changes color depending on the pH of the solution, ranging from red (acidic) to green (neutral) to purple (basic).
Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
The answer will depend on which indicator is being used.
If you are testing with Universal Indicator or the Litmus Test it will turn red.
Maybe you used fresh coconut (which holds a lot of water)?
This is because most likely, the indicator was a PH indicator, plain water has a neutral to low Ph indicated by blue. Whereas when vining air is added it increases the acidity of the solution as indicated by the pink color.
When an indicator is added to water, it changes color based on the pH level of the water. Indicators are substances that change color depending on whether the solution is acidic, basic, or neutral. This change in color helps to determine the pH level of the water.
