Identify which unknown was observed to be a basic salt (give the letter and chemical identity). Write the chemical reaction that is responsible for the increase in pH by this compound. Saved

The unknown compound is Na2CO3(Sodium carbonate).

Explanation:

The chemical compound Na2CO3 is known as Sodium carbonate. It has the value for Molar mass to be 105.9888 g/mol, the Density value to be 2.54 g/cm³ and the Melting point and boiling point values to be 851 °C and 1,600 °C respectively.

The chemical compound that is sodium carbonate is also known as the basic salt.

The chemical compound is also used in water softening and it is this process that causes the changes in pH value.

When added to water, the pH rises that is to say it becomes more basic.

The chemical reaction that is responsible for the increase in pH by this compound is given below;

Step one:

Na2CO3(s) > Na2CO3(aq).

Step two:

Na2CO3(aq) > 2Na^+ + CO3^2-.

Step three:

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

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

there all right good
