If A scientist pours 3.48 ML of hydrochloric acid into a beaker How many liters of hydrochloric acid did the scientist pour into the beaker?
The scientist poured 0.00348 liters of hydrochloric acid into the beaker.
Which safety symbols would you expect to see for an experiment that requires the use of acid?
You would expect to see safety symbols for corrosive substances or chemicals, such as the corrosive symbol (a skull and crossbones inside a diamond) or the acid symbol (a beaker with a drop of liquid). Additionally, you may also see symbols indicating the need for personal protective equipment like gloves, goggles, and lab coats.
What happens to the pH in the beaker as the acid is added?
The pH in the beaker will decrease as the acid is added, indicating an increase in acidity. This is because the acid donates hydrogen ions, which lowers the pH of the solution.
What is floating in the beaker in Dr. Finkelstein's laboratory?
Sulfuric acid is floating in the beaker in Dr. Finkelstein's laboratory. The swirling green liquid contains sulfuric acid, a highly corrosive substance.
How should the pH of a material in the Acidic beaker compare to that in the Basic beaker before any acid or base is added?
The material in the acidic beaker should have a lower pH compared to the material in the basic beaker before any acid or base is added. This is because the acidic beaker contains an excess of hydrogen ions, resulting in a lower pH, while the basic beaker contains an excess of hydroxide ions, leading to a higher pH.

Is it acid into base or base into acid?
The answer might depend on what kind of solution you are talking about. If you start with water and add acid, you get a dilute solution of acid, then a more concentrated solution as you add more. If you started pouring water into acid, you would initially get a very concentrated solution, then diluter as you add more water. If you are in the lab with a beaker of acid and a beaker of water and need to mix them, always pour the acid into the the water, not the other way around. The mixing generates heat. There is a slight chance that the beaker could break or get knocked over just after you start mixing. Spilling hot acid with a little bit of water is far more dangerous than spilling hot water with a little bit of acid.
What is the substance remaining in the beaker after evaporaiting the excess acid of hydrochloric acid with manganese?
This compound is the manganese dichloride.
A sample of zinc metal is placed in a beaker and What if your teacher gives you one chance to dissolve the zinc and produce hydrogen gas She places four choices of chemicals to complete this task?
To dissolve the zinc and produce hydrogen gas, you would likely use hydrochloric acid, sulfuric acid, nitric acid, or acetic acid. These acids can react with the zinc metal in the beaker to produce zinc salts and hydrogen gas through a chemical reaction. It's essential to handle these chemicals carefully and follow safety procedures under your teacher's supervision.
What precautions should be taken when using 6.0m HCl?
1.) Safety glasses to shield your eyes from any contact with acid 2.) Pouring the solution ( into maybe a conical flask, beaker etc.) at eye level to avoid spillage.
What is the safety rule for diluting an acid?
Wear safety goggles, do not mix acids unless instructed to do so.
Should you use high amount of weak acid or low amount of strong acid?
From safety point of view it is better to use high amount of weak acid other wise it would be better to use strong acid if human safety is not issue due to use of scientific equipments
