Why is Na2CO3 alkaline in nature?
Because it contains sodium cations, which are strongly basic, and carbonate anions which are weakly acidic. So the basic ions win over acidic ions, making Na2CO3 alkaline(i.e. basic).
Will polonium make cations or anions?
cations
How you can tell the difference between an acid and an alkali?
The pH of an acidic solution is under 7; the solution contain cations H+. The pH of an alkaline solution is above 7; the solution contain anions OH-.
In an aqueous solution cations are attracted toward what?
Cations are attracted to anions.
How do you tell apart cations and anions?
cations, positively charged ions, can be told from anions, negatively charged ions, bysize--cations are smaller then the average atomic mass of the element --anions are largertype--cations are made from metals --anions are non-metalsorder--cations are always listed first in a chemical equation
What are the cations found in an acidic solution?
nothin
What is exchangeable acidity?
Exchangeable acidity is a measure of the amount of a soil's cation exchange capacity (CEC) that is occupied by acidic cations. By acidic cations, soil scientists generally mean H+ and Al3+, but it can also include Fe and Mn cations. Aluminum and iron cations will combine with OH- ions and take it out of solution, forming an insoluble compound. Exchangeable acidity is typically reported as a percentage of CEC, or in milliequivalents/100 g of soil.

Is Strontium oxide acidic or basic?
Strongly basic.As the size of 2+ cations increase down the alkaline group basicity increases.

How are acids related to electrolytes and electrical conductivity?
Acids in aqueous solution are almost always electrolytes that produce hydrogen cations in the solution. Hydrogen cations have the highest specific conductance of any ions in aqueous solution, so that acidic solutions are very strongly conductive if concentrated.
Do alkali metals generally make anions or cations?
Cations.
Is a flame test for cations?
yes, for cations
Will polonium make cations or anions?
cations
Are cations metals?
cations, they all ionize to a positive charge cation=+ charge anion=- charge
What are metal cations?
Cations are ions with a positive charge. Metal cations are formed when metal loses electrons.
