What do these words mean?

Question

Im confused- whats these-
spectator ions
ions
neautrilisation

i looked them up onyahoo but they just used themin sentences, ineed some sort of dictionary explanation

Answer 1

A spectator ion is an ion that exists as a reactant and a product in a chemical equation. Spectator ions can be observed in the reaction of aqueous solutions of sodium chloride and copper (II) sulfate:

2Na+(aq) + 2Cl−(aq) + Cu2+(aq) + SO42−(aq) → 2Na+(aq) + SO42−(aq) + CuCl2 (s)
The Na+ and SO42− ions are spectator ions since they remain unchanged on both sides of the equation. They simply "watch" the other ions react, hence the name. In reaction stoichiometry, spectator ions are removed from a complete ionic equation to form a net ionic equation. For the above example this yields:

2Cl−(aq) + Cu2+(aq) → CuCl2 (s)
Common spectator ions include Na+, K+, and NO3−.

An ion is an atom, group of atoms, or subatomic particle that normally is electrically neutral and achieves its status as an ion by loss (or addition) of an electron. The simplest ions are the proton (a hydrogen ion, H+, positive charge), and alpha particle (helium ion, He2+, consisting of two protons and two neutrons).

I hope you appreciate this as my brain is now hurting :o)

Answer 2

sound like you are learning about acids and bases. Tricky subject!

Ok, an ion is an atom that has lost or gained one or more charges. Remember that all ATOMS are neutral.
So, taking Hydrogen as an example, the atom is a proton plus one electron. This is a neutral charge.

But, if a hydrogen atom loses its electron (and it does this very easily - its the most absentminded element!), it becomes just a proton : H+. This is an ION: an atom that has lost or gained an electrical charge.
It now has a positive charge of +1. The electron it lost is a negative charge of -1.

Acids are substances that will lose a proton into water to form a solution that is rich in hydrogen ions (H+). Bases are substances that lose an OH - in solution.

If you have a beaker of hydrochloric acid (HCl), and pour it into water, the HCl will break apart (ionise) into H+ and Cl - ions. The water will take up some of the H+ or release some OH, but the Cl is ignored. This is the spectator ion. It is formed, but takes no part in a chemical reaction. It is just watching from the sidelines while everyone else gets involved!

If you have an equal amount of HCl and an equal amount of NaOH, and add them together they will react. The hydrogen ion will make friends with the OH ion and form water (h2o). The Na and the Cl will get together and make a salt. The solution is now no longer acidic or basic - it has turned into water and salt. It has been neutralised.

Answer 3

A spectator ion is an ion that exists as a reactant and a product in a chemical equation. Basically, it's an ion that is on both sides of the equation and remains unchanged.

An ion is a charged subatomic particle. It's one of the things that makes up an atom.

Neutralization is the act of being neutralized which means to be made neutral, being neither positive nor negative.

I got these answers from Merriam-Webster Online Dictionary and wikipedia. You can find very good information on nearly everything at these two sites. Here are the links below:

Answer 4

OK an ion is a particle that is charged. For example salt NaCl is made up of positively charged Sodium ions (Na+) and negatively charged Chloride ions (Cl-).

A spectator ion is something that is present within a reaction but at the end of the reaction it is the same as it was at the beginning.

Neutalisation is what occurs when you mix acid and bases. They neutralise each other and bring the pH to 7.

I usually find looking on wikipedia is more helpful than doing a yahoo search as they give definitions and explanations of the thing you are searching for.

Hope this helps

Answer 5

So sorry I did look up for you in my dictionary and could not find anything spelt the way you have spelt them. Are you sure of spellings.
Nearest I can think of out of top of head is
1: Observers IE more than one person
2: something to do with eletcricity.
3: to render or become neutral by counteracting mix ect.
Is is a chemistry question by any chance if it is it is to do with making something and others observe??
Sorry could not be any better but been over 30yrs since at school and hated chemistry.

Answer 6

An ion is a charged particle - that is to say an atom that has either gained or lost an electron, thereby altering the electric charge of the atom.

Been too long since I did by A-level Chem & Physics. If you want, I'll try and find out?

Answer 7

spectator ion (′spek′tād·ər ′Ä«′än)
(chemistry) An ion that serves to balance the electrical charges in a reaction environment without participating in product formation.

i·on (ī'ŏn', ī'ən)
n.
An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons.

neu·tral·i·za·tion (nū'trə-lĭ-zā'shən, nyū'-)
n.

The act or process of neutralizing.
The state or quality of being neutralized.
Chemistry. A reaction between an acid and a base that yields a salt and water.

Answer 8

No idea look them up in dictionary.

Answer 9

something about chemistry-i studied that last year, now i can't remember

Answer 10

they mean its time for you to put your colouring pencils away
and get to bed so you can get up early tomorrow for school
