Is it important to dry a beaker before collecting a solution?
Yes, it is important to dry a beaker before collecting a solution as any remaining liquid in the beaker could dilute the solution being collected, affecting the concentration and accuracy of the solution. Drying the beaker also helps to ensure that the solution is not contaminated by any residual water or impurities from the beaker.
Why beaker used to collect solution should be dry?
Beakers that will be used to collect solutions should be completely dry before use due the possibility of water being able to dilute the solution that will be placed inside of the beaker. If a beaker is not completely dry before collection of a solution, an inacurracy in data results may occur.
Why do you use conical flask in the titration process rather than beaker?
Conical flasks have a narrow neck that helps prevent splashing and allows for more controlled pouring of reagents. This makes them ideal for precise measurements and additions during titration. The conical shape also allows for easy swirling of the solution without spilling.
What is it called when the solution settle to the bottom of a beaker?
hotter
34. If liver cells are put in a beaker with a solution containing the same solute concentration as that found inside the cell the beaker would contain a(n)?
If liver cells are placed in a beaker with a solution that has the same solute concentration as the inside of the cells, the beaker would contain an isotonic solution. In this scenario, there would be no net movement of water into or out of the cells, maintaining their shape and function. The cells would remain stable, as the osmotic pressure is balanced.
What changes in egg when placed in saltwater solution?
the egg become bigger if they put in vinegar and beaker
What information is needed to track the velocity of an ocean current?
vinegar is added to the beaker of baking soda and water. if the reaction is exothermic, what will happen?
What is an inverted beaker?
An inverted beaker is simply a beaker turned upside down. This position prevents the contents inside the beaker from spilling out or from being contaminated by outside substances. It is commonly used in labs to cover or protect the contents of the beaker.
What would happen if a strip of blue litmus paper is placed in a beaker of vinegar?
When a blue litmus paper are put in a solution of baking soda and the conditions are under the basic ph level, it will turn into red. And if a red litmus paper is put under acidic conditions, it will turn into blue.

Is baking soda an alkaline or acid?
Yes. And if you add it too vinigar it makes smoke. You take a balloon and fill 1/5 of it with baking powder. You then only set the top of the balloon around a beaker filled 1/4 of the way with vinegar. Then hold the balloon up right and let the baking powder mix with the vinegar. It will blow up the balloon on it's own. It's actually pretty cool.
How could you determine the effect of temperature of the rate of the chemical reaction between baking soda and vinegar?
For this you would need a stopwatch and the ingredients for the reaction. Now take vinegar in a beaker and keep the stopwatch in one hand. take a pinch of baking soda in the other hand. Now drop it in the vinegar solution and simultaneously start the stopwatch. Note the time taken for the bubbling to stop completely. Now raise the temperature and repeat the same experiment. Do this for 5 set of reading by raising the temperature 5 degrees each time. Now do this by decreasing the temperature 5 degrees. Tabulate the data and think about the answer.
How do you make a small volcano?
MATERIALS: Well first of all get a cylinder beaker, any size you wish. Then molding clay, as well as vinegar, baking soda, food coloring (red, preferred), and paint (brown or gray).DIRECTIONS: Place the cylinder beaker on a flat surface. Then put the molding clay over the surface of the beaker but leave a hole where the mouth of the beaker is. Then paint the clay but THE CLAY HAS TO BE DRIED BEFORE PAINT IS APPLIED! Once that's over, put in 2 tablespoons of baking soda in the hole at the top, also put in a couple of drops of the food coloring. And when ready for the volcano to erupt pour in 3 tablespoons of vinegar fast. SO HAVE IT READY! Have fun and Enjoy!

If A beaker contains 100 grams of 1.7 M NaCl and you transfer 50 grams what is the molarity of the solution in the beaker?
After transferring 50 grams of the 1.7 M NaCl solution to a new beaker, the final amount of NaCl in the original beaker will be 50 grams. To find the new molarity, you would first calculate the new moles of NaCl in the beaker, then divide by the total volume of the solution in liters. The molarity will be reduced in the original beaker due to the dilution from transferring a portion of the solution.
Why is it important to let the sand settle first at the bottom of the beaker before pouring the solution into another beaker?
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
Would a drop of vinegar sink or float beaker full of glycerin?
sure!!
