review acids and bases

After students are finished using LiOH in a lab experiment, the teacher needs to neutralize the base with an acid before dumping it down the drain to dispose of it. This can be seen in the equation below. HCl + LiOH --> LiCl + H₂O What is the name of the acid that the teacher used to neutralize the base?

• nitrous acid

• chlorous acid

• hydrochloric acid

• chloric acid

Bases are crucial in various applications, such as neutralizing acids. Potassium hydroxide, for example , is commonly used in production of liquid soap due soaps due to its ability to react with oils. What is the chemical formula for potassium hydroxide.

• NaOH

• KOH

• K₂OH

• KCL

According to the bronsted-lowry theory, what is the role of water (H₂O) in the reaction below? HNO₃ + H₂O → NO₃⁻ + H₃O⁺

• H₂O is a base because it gained H⁺

• H₂O is an acid because it gained OH⁻

• H₂O is an acid because it lost H⁺

• H₂O is a base because it lost OH⁻

When dissolved in water, Beryllium hydroxide forms a baseic solution. Which ion's concentration increases in the solution, classifying beryllium hydroxide as an Arrenius base?

• hydrogen ions

• oxide ions

• hydroxide ions

• berryllium ions

The diagram below shows a 0.1 M aqueous solution of HCl and a 0.1 M aqueous solution of HNO₂. Using the diagram above, which solution contains a stronger acid?

• Beaker 1 : HCl

• neither

• There is not enough information

• Beaker 2 : HNO2

Which of the following compounds is an example of a strong base?

• H₂S

• NH₃

• HCl

• Ca(OH)₂

Why is LiOh considered a strong base?

• Because a strong base partially dissociates in water

• Because a strong base dissociates completely in water

• becaise it is has hydroxide ions

• because the pH is low

Which equation represents a neitralization reaction?

• Na₂S + 2HCl → 2NaCl + H₂S

• BaCl₂ →Ba + Cl₂

• HI + AgOH → AgI + H₂O

• Zn + CuCl₂→ ZnCl₂ + H₂

If a person is suffering from heartburn from hydrochloric acid, he consumes an antacid containing magnesium hydroxide to neutralize the reaction. What are the resulting products?

• KCl + Br₂

• MgCl₂ + 2H₂O

• CaO + H₂O

• C + O₂

The water from a thunderstorm has a very low pH. a low pH indicates which of the following about water?

• It has a high concentrations of H+ ions

• It has a high concentrations of hydroxide ions

• it has equal concentration of H+ and OH- ions
