How do you find out if an element's atom is cation or anion?
Q. I already know how to find out its shell, protons and electrons, but how do i find out if the atom is cation or anion?
Asked by Jack D - Sun Mar 1 18:40:12 2009 - - 1 Answers - 0 Comments
A. A cation is a metallic atom that has lost electrons and thus has a positive charge. It moves to the cathode of a circuit. A anion is a non-metallic atom that has gained electrons and therefore has a negative charge. It moves to the anode of a circuit.

Does an anion play any role in a flame test?
Q. (I'm doing a chemistry lab tomorrow) I know that flame test is for detecting a metal cation by observing the color it emits. But does an anion play any role in the color of the flame? Thanks Also, if one of the colors doesn't match up exactly to something on the spectrum, what does that mean? What causes that?

A. No anions play a role in flame tests. Also some colors don't match up. 1) We are humans and what one person may see isn't what another person sees. 2)Also there may be some contamination in the chemical sample which may throw the color off some. That is why flame tests aren't the best test to check for the presence of certain ions present.

How do I determine how many charges are in a cation and anion?
Q. In Chemistry how do you know the total charge of cations and anions of elements? I have a chart but some of the elements don't show the total charge or 2 possible charges. For example, my chart shows Mg has a 2+ charge. But Fe could be 2+ or 3+? How do I determine which one? Also I can't find a charge for group 4A or 5A does that mean there is no charge and the compound would be covalent? Thanks for any help!
Asked by momoftwo - Mon Jun 16 11:18:58 2008 - - 3 Answers - 0 Comments
A. Cations and anions need to balance in terms of charge. If you don't know the charge of part of the molecule, find the charge of the other. If you are trying to decide if the charge on iron is +2 or +3, look to see what the negative charge on the other part of the molecule is. If it's -2, you have Fe(II). If it's -3, you have FE(III). The Department of Chemistry and Physics at Arizona State has a pretty thorough list.

Q. I have determined the anion to be phosphate (PO4) using a precipitate test. What tests can I use to find the cation? other details: -the solution is basic -the cation is either Li, Na, K, Ca, Sr, or Ba -the solution is mostly clear with a white milky substance that tends to settle a bit
Asked by jd - Tue May 22 21:52:23 2007 - - 3 Answers - 0 Comments
A. Sodium & potassium phosphates are totally soluble over wide pH range (lithium therefore probably also) Calcium phosphate (& therefore probably also barium & strontium) are not soluble above about pH 4. Dry some solution in a pyrex beaker or evaporating dish in an oven. Test the residue in a hot colourless flame on a stainless spatular or on a platinum wire. Sodium gives orange-yellow flame, potassium violet flame, calcium & strontium intense red flame. Not sure about the others. Check your text books.

A. If you look at a salt with a cation from a base and an anion from an acid, you can determine whether that salt will be acidic or basic. However, the cation and anion itself isn't acidic/basic. for example, if you have a salt NaCl, you have to look at the root of it (original acid and base) Na is from NaOH and Cl is from HCl. Since both of these are strong acid and base, this salt will be neutral. However, if we have a salt like NaF, the root base is NaOH-a strong base, and the root acid is HF, which is a weak acid. Therefore, this salt is a basic salt. If both the root acid and base are weak, you have to look at the Ka and Kb of the conjugate base/acid of the original acid/base. If Ka > Kb, then it's an acidic salt. If Ka < Kb, it's a… [cont.]

A. Metabolic acidosis is acid accumulation from increased acid production or acid ingestion, Causes are classified by their effect on the anion gap . The Anion Gap is an approximate measurement of ions, that is molecules with a charge, either negative or positive.The most common causes of a high anion gap metabolic acidosis are Ketoacidosis,Lactic acidosis, Renal failure, Toxic ingestions.

Asked by DOODLES - Sat Nov 22 19:05:51 2008 - - 3 Answers - 0 Comments
A. You could do a cat-scan. Cations tend to purr loudly and sleep at the foot of your beaker. Oh for heaven's sake. A cation is a positively charged ion and an anion is a negatively charged ion. Cations are attracted to the cathode of a voltaic cell, and anions are attracted to the anode. Remember it this way: ANIon = A Negative Ion. === Follow up === You wrote: "okay i know the difference but for example is Copper (II) Chloride an cation or anion?" Obviously, you don't know the difference. Copper (II) chloride is a compound. When it dissociates in water then it splits apart into two ions, copper (II) ions, which are cations, and chloide ions, which are the anions. But the compound itself is neither an cation, nor an anion.

A. Certain sizes of cations and anions can only fit into certain places in a crystal structure, which is very ordered. Consider a display of fresh oranges at your grocery store. They are all neatly piled up like a pyramid. Now, take one out (anywhere, including the middle of the pyramid) and try to replace it with a grapefruit. Screws things up, doesn't it? Now, try the same thing with an apple that is about the same size as one of the oranges. No problem. The grapefruit was an element that had a radius much too large to fit into the structure. The apple, even though it's not the same element as an orange, would fit in the place of an orange as long as its valence number was the same as the orange.
