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?
0.0038 liters
How do you dilute sulfuric acid safely?
Determine the concentration desired and then pour the needed amount of water into beaker. Add the the acid volume to this beaker full of water.
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 happens to the pH in the beaker as the acid is added?
The pH drops. The stronger the acid the lower the pH.
What is a titration and what equipment would you need?
A titration is a process of nutrilising an acid. You would need a burette, a beaker and and acidic and alkali substance. Higher chem FTW
What safety symbols would you see when you do an experiment that uses acid?
Chemical safety

What is the substance remaining in the beaker after evaporaiting the excess acid of hydrochloric acid with manganese?
This compound is the manganese dichloride.
Zinc is added to a beaker containing hydrochloric acid and the beaker gets warm. What type of reaction is this?
Exothermic, because energy is released.
How do you Pour Acid?
down the side of the beaker so it doesn't splash
What is the pH of pure water in the beaker before the acid is added?
7
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?
They would both contain the same neutral pH of pure water = pH of 7.0; neither acidic nor basic.
What is the safety rule for diluting an acid?
Wear safety goggles, do not mix acids unless instructed to do so.
