Write the balanced equation for each reaction. Phases are optional.

(1) The carbonate ion (CO2−3) acts as a Brønsted base with water.
(2) The carbon-containing product from the first reaction acts as a Brønsted base with water.
(3) The carbon-containing product from the second reaction decomposes into carbon dioxide gas and water.

Consider the products of the reactions. When the carbonate ion reacts with water, is the resulting solution acidic or basic?

The resulting solution is a basic solution because of the presence of the bicarbonate ion and the hydroxide ion in the products.

The reaction between the carbonate ion which acts as a Brønsted base with water is shown as;

CO3^2- + H2O > HCO3^- + OH^-

The carbon containing product of this reaction is the bicarbonate ion acts as a Brønsted base  which reacts with water as follows;

HCO3^- + H2O > H2CO3 + OH^-

The carbonic acid from the reaction above decomposes according to the reaction equation;

H2CO3 > CO2  +  H2O

When carbonate ion reacts with water, the resulting solution is a basic solution because of the presence of the bicarbonate ion and the hydroxide ion in the products.

1. CO₃⁻²  +  H₂O  ⇄  HCO₃⁻  +  OH⁻

2. HCO₃⁻ +  H₂O  ⇄  H₂CO₃  +  OH⁻  

3.  H₂CO₃ →  H₂O  + CO₂

Basic solution

Explanation:

Brønsted Lowry theory:

Acid → Release a proton

Base → Accept a proton

1. CO₃⁻²  +  H₂O  ⇄  HCO₃⁻  +  OH⁻

Carbonate takes a proton from the water

2.  HCO₃⁻ +  H₂O  ⇄  H₂CO₃  +  OH⁻  

Bicarbonate takesa proton from the water to produce carbonic acid.

3. H₂CO₃ →  H₂O  + CO₂

Carbonate acid decomposes into CO₂ and H₂O

In the first reaction, when the carbonate takes a proton from the water, water releases OH⁻, so the solution is basic.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
