Understanding Dissociation of Acids, Bases, and Salts

The video tutorial by Tatiana Gennadievna Belousova explains the dissociation of acids, bases, and salts in water. It covers the process of dissociation, the properties of acids and bases, and the unique characteristics of salts. The tutorial also highlights the importance of understanding ion charges and the use of solubility tables. The lesson concludes with a summary of the key points discussed.

What is the primary characteristic of an electrolyte?

• It does not conduct electricity.

• It can dissociate into ions in water.

• It can dissolve in oil.

• It is always a solid at room temperature.

Which of the following is a common property of acids?

• They have a bitter taste.

• They are always solid.

• They turn litmus paper blue.

• They have a pH less than 7.

How does sulfuric acid (H2SO4) dissociate in water?

• It dissociates in one step into H+ and SO4 2- ions.

• It dissociates into H2 and SO4 ions.

• It dissociates stepwise, first releasing one H+ ion.

• It does not dissociate in water.

What is a common property of bases?

• They have a sour taste.

• They have a pH greater than 7.

• They turn litmus paper red.

• They are non-reactive.

Which ion is commonly formed when bases dissociate in water?

• Na+

• OH-

• Cl-

• H+

What happens to sodium chloride (NaCl) when it dissociates in water?

• It forms NaCl2 ions.

• It remains as NaCl molecules.

• It forms Na2+ and Cl2- ions.

• It forms Na+ and Cl- ions.

What type of salt is potassium hydrogen sulfate (KHSO4)?

• Double salt

• Acidic salt

• Basic salt

• Neutral salt

Which of the following is NOT a property of salts?

• They can be sweet, sour, or salty.

• They dissociate into metal and non-metal ions.

• They have a fixed set of properties.

• They can be formed from acids and bases.

What is the significance of the pH value in determining the strength of an acid or base?

• A higher pH indicates a stronger acid.

• A lower pH indicates a stronger base.

• A pH closer to 7 indicates a stronger acid.

• A pH further from 7 indicates a stronger acid or base.

What is the main takeaway about the dissociation of acids, bases, and salts?

• Only acids dissociate in water.

• All dissociate in the same way.

• None dissociate in water.

• Each has unique dissociation properties.
