Which ion in periodic table used in the body?
sodium potassium calcium iron
What is an example of an ion of biological importance?
Sodium in one, but so are potassium and calcium.
How do you convert dichromate ion into chromate ion?
Conversion is increased when the pH increase.
How do we convert dichromate ion into chromate ion?
The conversion increase when the pH increase.
Which element or ion will spontaneously react with Ca?
Chlorine reacts readily with calcium. Calcium donates two electrons to this ionic bond and chlorine accepts one electron from calcium into its valance shell, so you need two chlorines to react with calcium. Ca(2+) and Cl- = CaCl2 Calcium chloride
What is it ion chromate?
The chromate ion is CrO42-
Which compound names end in ate?
Compound names that end in -ate contain oxygen.Ionic CompoundsCaCO3 contains the carbonate ion, CO32-, and is called calcium carbonate.KNO3 contains the nitrate ion, NO3-, and is called potassium carbonate.Na3PO4 contains the phosphate ion, PO43-, and is called potassium phosphate.MgCrO4 contains the chromate ion, CrO42-, and is called potassium chromate.CaSO4 contains the sulfate ion, SO42-, and is called calcium sulfate.Acids containing oxygenH2CO3 is carbonic acidHNO3 is nitric acidH3PO4 is phosphoric acidH2CrO4 is chromic acidH2SO4 is sulfuric acid
Why does potassium form a 1 plus ion while calcium forms a 2 plus ion?
potassium is in group 1 and calcium in group 2, so potassium has 1 valence electron and calcium 2.
Symbol for dichromate?
Potassium chromate is K2CrO4 Potassium dichromate is K2Cr2O7
What is the symbol and charge for the ion chromate?
The formula for a chromate ion is CrO4-2, and its charge is -2.
Which metal ion is reduced by lead?
Calcium, mercury, cadmium, or potassium?
