The pH drops. The stronger the acid the lower the pH.
It will evaporate
Hydrochloric acid will turn pH paper red or pink when a few drops are added. This color change indicates that the acid is acidic, with a pH typically below 4.
If you mix albumin with 5 drops of biuret reagent, the resulting color would most likely be a purple hue. This color change occurs due to the presence of peptide bonds in the protein, which react with the biuret reagent to form a colored complex.
When 20 drops of bromthymol blue are added to distilled water in a beaker, the solution will change color depending on the pH level of the water. Bromthymol blue is a pH indicator that turns yellow in acidic conditions (pH below 6) and blue in basic conditions (pH above 7), while it remains green in neutral conditions (around pH 7). Since distilled water is typically neutral, the solution will likely appear green. However, if there are any impurities or if the water's pH is altered, the indicator may show a different color.
This happens when the contents of the beaker are colder than the surrounding air. This causes water vapor in the warmer air to drop below its dew point and condense onto the outside of the beaker.
Condensation will collect on the outside of the beaker when you put a 5 ml of water and ice cubes inside due to the temperature difference between the cold contents inside the beaker and the warmer air outside. This causes water vapor in the air to condense, forming droplets on the exterior surface of the beaker.
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
Add one tsp. or vinegar and 15 green drops of food coloring and 5 drops of blue food coloring into 1/2 cup of boiling water. Dip hard, cooked eggs into water for 5 minutes or longer. Once the dye has dried, it won't come off. You can add a few more drops of blue to get a more turquoise color.
Indicators are used in drops during titration to detect the endpoint of the reaction, which is when the reaction has reached completion. The indicator changes color when the pH of the solution changes, indicating that the correct stoichiometric amount of titrant has been added to the solution being titrated.
