In the high ion equation, the micro-sol matter is not removed as a reactant, just like the ionic formula of MgCo3 reacting with HCl Please write down the ion equation for this reaction In the high ion equation, the micro-soluble matter is not removed as a reactant, just like the ionic formula of MgCo3 reacting with HCl Write down the ion equation for this reaction In the high ion equation, the micro-solutions are not removed as reactants, just like the ionic formula of MgCo3 reacting with HCl Write down the ion equation for this reaction
In high school chemistry, there is only one case in which micro-solubility is not removed, that is, the solubility of the substance is smaller (in fact, these rules are for the test, it is not meaningful to remove);
So, when MgCO3 and HCl are react,
MgCO3+2H+-----> Mg2++CO2(gas)+H2O;
When MgCO3 is reacted with CaCl2,
CO3(2-)+ Ca2+-----> CaCO3
