  3. chloride

  4. none of the above

Show answer
Correct Option: C
Explanation:

Chloride
Hydrochloric acid reacts with Carbonate to form chlorides.
$2HCl+CaCo _3\rightarrow CaCl _2+H _2O+CO _2$

$2HCl{(aq)} + MgCO _{3}(s)\rightarrow$

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. $MgCl _{2}(aq) + CO _{2}(g) + H _{2}O(l)$

  2. $MgCl _{2}(aq) + CO _{2}(g)$

  3. $MgCl _{2}(aq) + H _{2}O(l)$

  4. $MgCl _{2}(aq) + CO _{2}(g) + 3H _{2}O(l)$

Show answer
Correct Option: A
Explanation:

$(A)$  $MgCl _{2}(aq)$ + $CO _{2}(g)$ + $H _{2}O(l)$


$Reaction$ : $2HCl(aq)$ + $MgCO _{3}(s)$ $\rightarrow$ $MgCl _{2}(aq)$ + $CO _{2}(g)$ + $H _{2}O(l)$

_________ causes bubble formation when acid reacts with carbonates.

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. Salt

  2. $CO _{2}$

  3. Water

  4. Oxygen

Show answer
Correct Option: B
Explanation:

When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble) a salt, water and carbon dioxide are made. Carbon dioxide is formed as by product which causes bubbling during the reaction and can be detected using limewater.
$Acid + Metal\ carbonate \rightarrow Salt + Water + Carbon\ dioxide$

$H {2}SO _{4} + CuCO _{3} \rightarrow$ ___ $ + H _{2}O + CO _{2}$

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. $CuSO _{4}$

  2. $CuSO _{3}$

  3. $CuSO _{2}$

  4. None of above

Show answer
Correct Option: A
Explanation:

All carbonates react with acids to produce salt, water and carbon dioxide gas. 
$H _{2}SO _{4} + CuCO _{3} \rightarrow CuSO _{4} + H _{2}O + CO _{2}$

What is formed when acids react with carbonates?

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. Salt

  2. Water

  3. Carbon dioxide

  4. All of above

Show answer
Correct Option: D
Explanation:

When acids react with carbonates, such as calcium carbonate (found in chalk, limestone and marble), a salt, water and carbon dioxide are made. In general:
$Acid + Metal\ carbonate \rightarrow Salt + Water + Carbon\ dioxide$

What does an acid give when they react with metal hydrogen carbonate?

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. $C{O} _{2}$

  2. ${H} _{2}O$

  3. Salt

  4. All of above

Show answer
Correct Option: D
Explanation:

Acids give carbon dioxide gas, respective salt and water when they react with metal hydrogen carbonate.
Acid $+$ Metal hydrogen carbonate $\rightarrow$ Salt $+$ Carbon dioxide $+$ Water.

Why does baking soda and vinegar react with each other?

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. Undergo acid base reaction

  2. Exchange atoms

  3. Both $(A)$ and $(B)$

  4. High temperature

Show answer
Correct Option: C
Explanation:

Baking soda and vinegar react with each other because of an acid-base reaction. Baking soda is a bicarbonate $(NaHCO _{3})$ and vinegar is an acetic acid $(HCH _{3}COO)$. One of the products this reaction creates is carbon dioxide. Also Baking soda and vinegar react with each other because they exchange atoms. In this case, they are exchange a proton, which is a subatomic particle that makes atoms.

When sulphuric acid reacts with calcium carbonate, ________ is formed.

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. calcium sulphate

  2. calcium

  3. calcium hydroxide

  4. hydrogen gas

Show answer
Correct Option: A
Explanation:

Sulphuric acid gives calcium sulphate, carbon dioxide gas and water when it reacts with calcium carbonate.
$CaC{O} _{3}   +   {H} _{2}S{O} _{4}   \rightarrow   CaS{O} _{4}   +   C{O} _{2}   +   {H} _{2}O$.

Why do the gas released when metal bicarbonates react with acid turns lime water milky?

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. Formation of calcium hydrogen carbonate

  2. Precipitation of calcium hydrogen carbonate

  3. Formation of white calcium carbonate precipitate

  4. None of above

Show answer
Correct Option: C
Explanation:

When metal bicarbonates react with acid liberates carbon dioxide The gas evolved because of reaction of acid with metal carbonate or metal hydrogen carbonate turns lime water milky. This shows that the gas is carbon dioxide gas. This happens because of formation of white precipitate of calcium carbonate.
$Ca{\left(OH\right)} _{2}  + C{O} _{2}    \Rightarrow   CaC{O} _{3}  +  {H} _{2}O$.

$HCl  +  NaHC{O} _{3}\rightarrow$
The given reaction releases which of the following gas?

chemistry acids and alkalis acids with carbonates reactions of acids and bases properties of acids and bases

  1. ${O} _{2}$

  2. $C{O} _{2}$

  3. ${H} _{2}$

  4. ${Cl} _{2}$

Show answer
Correct Option: B
Explanation:

Acids react with metal hydrogen carbonates and form corresponding salts, carbon dioxide and water. 
Example:
Hydrochloric acid on reaction with sodium bicarbonate forms sodium chloride, carbon dioxide and water.
$HCl  +  NaHC{O} _{3}  \rightarrow   NaCl  +  C{O} _{2}  +  {H} _{2}O$.
