acids with metals carnonates Flashcards
(12 cards)
What is produced when metal carbonates react with acids?
Salt, carbon dioxide, and water
The general reaction can be summarized as: Metal carbonate/Metal hydrogencarbonate + Acid → Salt + Carbon dioxide + Water
What are the products of the reaction between sodium carbonate and hydrochloric acid?
Sodium chloride, water, and carbon dioxide
The reaction is written as: Na2CO3 + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g)
What happens to lime water when carbon dioxide is passed through it?
A white precipitate of calcium carbonate forms
The reaction is: Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)
What is the effect of passing excess carbon dioxide through lime water?
Calcium bicarbonate is formed
The reaction is: CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)
What is the general reaction between a metal oxide and an acid?
Metal oxide + Acid → Salt + Water
What color does the solution turn when copper oxide reacts with hydrochloric acid?
Blue-green
This color change is due to the formation of copper(II) chloride.
What is a neutralization reaction?
The reaction between an acid and a base to give a salt and water
It can be generally written as: Base + Acid → Salt + Water
What is produced when sodium hydrogencarbonate reacts with hydrochloric acid?
Sodium chloride, water, and carbon dioxide
The reaction is: NaHCO3 + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g)
Fill in the blank: The reaction of an acid with a metal carbonate produces _____, carbon dioxide, and water.
Salt
True or False: All metal carbonates and hydrogencarbonates react with acids to produce the same products.
True
What does the reaction of a base with an acid demonstrate?
The effect of a base is nullified by an acid
Example: NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
