What piece of glassware is used to prepare very accurate concentrations of chemical solutions?
A volumetric flask is typically used to prepare accurate concentrations of chemical solutions due to its precise volume measurements. Volumetric flasks are designed to hold a specific volume of liquid at a specific temperature, making them ideal for preparing solutions with precise concentrations.
Is standard solution automated or manual?
Standard solutions can be either automated or manual. Automated standard solutions typically involve the use of laboratory equipment or instruments to prepare and dispense the solution, while manual standard solutions are prepared by hand using the appropriate equipment and techniques.
What is difference between stock and working solution?
A stock solution is a concentrated solution of a substance that is diluted to make working solutions of desired concentrations. A working solution is a solution ready for immediate use in an experiment or process. Stock solutions are typically stored for longer periods and used to prepare multiple working solutions.
How do use solutions to find the colors of the indicators?
First, identify the indicators used in the experiment. Then, prepare a set of solutions with known colors at different pH levels. Finally, compare the color change of the indicators with the color changes in the solutions to determine the pH of the solution being tested.
Does iodine dissolve best in water?
Yes, iodine is highly soluble in water. This property makes it easy to prepare solutions for various uses, such as disinfection or laboratory experiments.
What is the set of all points representing solutions is called blank of the equation?
solution
Can a metal dissolve into a liquid?
Yes. Metals can be dissolved into liquid solutions. Several metals can be dissolved in acidic media such as HNO3 to prepare acidic solutions of these metals.
What is chemistry mainly used for?
Chemistry is mainly used in laboratories to prepare chemical solutions and drugs.
What piece of glassware is used to prepare very accurate concentrations of chemical solutions?

Where do we usually use micropippetes?
For example pipettes are used in analytical chemistry to prepare samples for analysis or standard solutions.
What is blank l 4000 ml?
"Blank L 4000 ml" likely refers to a type of laboratory glassware or container, specifically a blank or empty vessel with a capacity of 4000 milliliters. It might be used for experiments, sample storage, or mixing solutions in a laboratory setting. The term "blank" can suggest that the container is free of any substances or prior samples, ensuring accuracy in measurements or experiments.

How do you prepare solution of different concert ration?
Take solution and mix different volumes with water as the final volume of all solutions is same
Why must solutions of starch be prepared on the day they are to be used?
Starch solutions should be prepared on the day they are to be used because they tend to degrade over time, leading to a decrease in viscosity and effectiveness. Repeated heating and cooling of starch solutions can also cause them to lose their thickening properties. It is best to prepare fresh starch solutions to ensure optimal performance.
Is standard solution automated or manual?
Standard solutions can be either automated or manual. Automated standard solutions typically involve the use of laboratory equipment or instruments to prepare and dispense the solution, while manual standard solutions are prepared by hand using the appropriate equipment and techniques.
