Can the amount of a solution affect the pH of that solution?
pH is the acidity. low pH is more acid, while high pH is more basic.
How can chemical reactions produce color change?
Simply put, the products are a different color from the reactants. For example, when copper reacts with a silver nitrate solution it turns the solution from colorless to blue. This is because while the silver ions (Ag+) do not affect the solution while the copper ions (Cu2+) released by the reaction are blue in the presence of water.
What should you use to record your data while carrying out an experiment?
A NoteBook
Why are standard solutions used?
A solution is a homogenous mixture of two or more substances. while A solution whose concentration is known is called a standard solution.
What is a hypothesies?

What is a reference solution in a chemistry lab?
The reference solution in a chemistry lab is the solution that is always present in the experiment, and it doesn't go away while you are testing other solutions. It is kind of like a base camp for your experiment; you're always starting off or going to include it.
Why must The Crucible by Arthur Miller be cooled in a desiccator?
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the experiment.
What does an obeservation means?
To make an observation is to watch the subject in question, for example if you were watching a bird, you would make observations as to what kinds of noises it makes, where it lives, does it have any chicks, what does it eat....those are all different kinds of observations. While performing an experiment, observations may include smells, weighing the object, what happens when another thing is added to the solution or whatever.

Who was the famous scientist who died stuffing a chicken with ice?
Francis Bacon died from the pneumonia he acquired while performing an experiment with a chicken and ice. He was attempting to see if snow would preserve meat in the same way that salt does.
Why is observation crucial while performing an experiment?
Well.... It's kinda dangerous, while you're pouring explosive chemicals together or dissecting a cow eye, to not be able to see. And I suggest that if you are going to cheat on your science homework, at least make it so it doesn't look like your homework. ;)

Does noise affect coordination?
Yes, it does, it distracts the brain from the task at hand. I did a science experiment, and most of my test subjects got a mild headache after threading a needle while listening to Nyan Cat (LOVE HIM!) I would DEFINITELY recommend this science experiment, it is VERY enjoyable!!!
What is the mediumor carrier substance through which the sound of the tuning fork travels to reach your ear?
Unless you are performing the experiment under water while swimming,the medium is almost always the air between the tuning fork and your ear.
