ion, proton
Explanation:
Ions and protons have profound relationships.
An ion is an atom that has lost or gained electrons.
A proton is a positively charged subatomic particle.
What is the relationship between an ion and a proton?
- In an atom, there are three fundamental particles.
- Protons are the positively charged particles located in the nucleus of atoms.
- Electrons are the negatively charged particles orbiting round an atom.
- Neutrons have no charges and they occupy the nucleus with protons.
Atoms are electrically neutral and this implies that they have equal number of protons and electrons.
In an ion, the number of protons and electrons differ.
For positive charged ions, the number of protons is more suggesting they have lost electrons.
For negatively charged ions. the number of protons is less suggesting they must have added electrons.
Compound are combinations of different atoms.

Answer:
Trial Number of moles
1 0.001249mol
2 0.001232mol
3 0.001187 mol
Explanation:
To calculate the <em>number of moles of tritant</em> you need its<em> molarity</em>.
Since the<em> molarity</em> is not reported, I will use 0.1000M (four significant figures), which is used in other similar problems.
<em>Molarity</em> is the concentration of the solution in number of moles of solute per liter of solution.
In this case the solute is <em>NaOH</em>.
The formula is:

Solve for the <em>number of moles:</em>

Then, using the molarity of 0.1000M and the volumes for each trial you can calculate the number of moles of tritant.
Trial mL liters Number of moles
1 12.49 0.01249 0.01249liters × 0.1000M = 0.001249mol
2 12.32 0.01232 0.01232liters × 0.1000M = 0.001232mol
3 11.87 0.01187 0.01187liters × 0.1000M = 0.001187 mol
You need to monitor the solution to see when the crystals start gathering at the bottom of the solution. You can slowly add alum until it stops dissolving. The point just before it starts its sedimentation at the bottom is the point when the solution is saturated.
