Why solutions cannot be stored in volumetric flask?
Volumetric flasks are designed to hold specific volumes of liquid accurately for dilution or mixing purposes. Storing solutions in a volumetric flask can lead to evaporation, contamination, and inaccuracies in concentration due to the narrow neck of the flask making it difficult to access the solution for further use. It is best to store solutions in appropriate containers designed for long-term storage.
The glassware used to titrate solutions is called?
The glassware used to titrate solutions is called a burette. It is a long, graduated tube with a stopcock at the bottom that allows for precise measurement and control of the volume of liquid added during the titration process.
What errors can occur by preparing a solution using cold water as a solvent?
The volume of any material depends on the temperature; to prepare water solutions (titrant, standard solution, control sample, etc.) for chemical analysis the normal and general accepted temperature is 20 oC for water. Also volumetric glassware is graduated at 20 oC.
What is function of volumetric cylinder?
A volumetric cylinder is used to accurately measure the volume of liquids. It typically has etched markings along its side to indicate different volume levels. The cylindrical shape and narrow neck of the cylinder help to ensure precise measurements.
Why salt solution is used in osmosis experiment?
Salt solutions are used in osmosis experiment to show that water will move to the side that has more salt. "Water follows salt."
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.
What is a volumetric flask and its uses?
A volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of glass or plastic and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is normally made in a chemically resistant plastic such as polypropylene rather than glass. The neck has a single ring graduation mark and a label. The label should show the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and the manufacturer’s logo. The glass or plastic is generally clear but may be amber colored for handling light sensitive compounds such as silver nitrate or vitamin A.
Why should heat resistant glassware be used when heating solutions?
Heat resistant glassware is designed to withstand high temperatures without shattering or leaching chemicals into the solution, making it safer for heating solutions. Using heat resistant glassware reduces the risk of breakage and contamination, ensuring the integrity of the experiment or process.
What is a flask and its uses?
Volumetric flask, also known as measuring flask or graduated flask, is a kind of glassware which is used for accurate dilutions and preparation of standard solutions. Volumetric flasks are usually pear-shaped with a graduation mark on the neck. The mark indicates the volume when the solution reaches there. Volumetric flasks are various in size, but they come in standard size, 10.00 ml, 25.00 ml, 50.00 ml, 100.0 ml, 250.0 ml, 500.0 ml, etc.
What precise volumetric equipment is used in titrations?
In titrations, precise volumetric equipment like burettes and volumetric flasks are commonly used. Burettes are used to deliver precise volumes of titrant, while volumetric flasks are used to prepare accurate standard solutions or to collect titrated solutions for analysis.
Why beaker is least accurate?
Beakers are typically least accurate because they lack precise volume markings and are not designed for measuring volumes. They are primarily used for approximate volume measurements and mixing solutions. For greater accuracy, other glassware such as graduated cylinders or volumetric flasks should be used.
Why solutions cannot be stored in volumetric flask?

Storing solutions in a volumetric flask can lead to evaporation, contamination, and inaccuracies in concentration due to the narrow neck of the flask making it difficult to access the solution for further use. It is best to store solutions in appropriate containers designed for long-term storage.
What are Volumetric flash and how are they used?
The volumetric flash is used to measure one specific volume. They are mostly used in mixing solutions where a one liter or one half a liter is needed.
The glassware used to titrate solutions is called?
The glassware used to titrate solutions is called a burette. It is a long, graduated tube with a stopcock at the bottom that allows for precise measurement and control of the volume of liquid added during the titration process.

Why use a volumetric flask for molar solutions?
Volumetric flasks are designed to accurately measure and hold a specific volume of liquid, making them ideal for preparing solutions with precise molarity. Their narrow neck and flat bottom ensure accurate measurements and minimize evaporation. This allows for consistent and reliable results in experiments that require precise concentrations of solutions.
What equipment qould be needed to perform this experiment?
To perform this experiment, you would need a spectrophotometer to measure the absorbance of the light passing through the solution, cuvettes to hold the solutions being tested, a light source to shine light through the solution, and the necessary chemicals and reagents for the specific experiment being conducted.
