Properties and Reactions of NaBr

The video tutorial explains how to determine if sodium bromide (NaBr) is acidic, basic, or neutral when dissolved in water. It begins by discussing the neutralization reaction between sodium hydroxide and hydrobromic acid, which forms NaBr and water. The video then examines the strength of the base (sodium hydroxide) and the acid (hydrobromic acid), both of which are strong. As a result, the NaBr solution is neutral with a pH of 7. The tutorial concludes by confirming that NaBr dissolved in water results in a neutral solution.

What is the main question addressed in the video regarding NaBr?

• Whether NaBr is a solid or liquid.

• Whether NaBr is a metal or non-metal.

• Whether NaBr can be used as a fuel.

• Whether NaBr is acidic, basic, or neutral in water.

Which two substances react to form NaBr in a neutralization reaction?

• Potassium hydroxide and hydrochloric acid.

• Sodium chloride and sulfuric acid.

• Sodium hydroxide and hydrobromic acid.

• Calcium carbonate and acetic acid.

What type of base is sodium hydroxide?

• Acidic compound

• Weak base

• Strong base

• Neutral compound

What type of acid is hydrobromic acid?

• Basic compound

• Strong acid

• Weak acid

• Neutral compound

What is the pH of a solution formed by a strong acid and a strong base?

• Less than 7

• Exactly 7

• More than 7

• Undefined

Why is the NaBr solution neutral when dissolved in water?

• Because it is formed from a weak acid and a weak base.

• Because it is formed from a strong acid and a strong base.

• Because it is a metal salt.

• Because it reacts with water to form an acid.

What is the final conclusion about the NaBr solution in water?

• It is basic.

• It is neutral.

• It is reactive.

• It is acidic.
