The concentration of ionic substances is important for the heart to beat. your heart responds to electrical impulses that travel through heart cells that are made up mostly of water. which properties of ionic compounds are important to support this function?

Answer is: conductivity in solution  and solubility in water.

Ionic compounds conduct electricity, because it dissociate in ions and ions conduct electicity.

Ionic substances dissociate in water on cations and anions. For example, dissociation of potassium chloride in water: KCl(aq) → K⁺(aq) + Cl⁻(aq).

Ionic compounds (most of the salts, strong acids and bases) dissolve in water because an ion-dipole interactions.

An ion-dipole is electrostatic interaction between a charged ion (cations and anions) and a molecule that has a dipole (in this example water).

Dipole is a separation of positive and negative charges. In water, hydrogen has positive and oxygen has negative charge.

answer is d because it is trust me

the answer would be a
