Unit 8 Though Shall not Forget

Front

What is the pH range for acids and bases?

Back

The pH of acids is less than 7, and the pH of bases is greater than 7.

Front

What is the pH of pure water at 25°C?

Back

The pH of pure water is 7 at 25°C.

Front

What do acids and bases do with [H+]?

Back

Acids donate [H+]; bases accept [H+].

Front

What is the hydronium ion?

Back

The hydronium ion is H3O+.

Front

What is [H+]?

Back

[H+] is a proton.

Front

Name some strong acids.

Back

Strong acids include HNO3, H2SO4, HClO4, HBr, HI, and HCl.

Front

What are strong bases?

Back

Strong bases include Group 1 hydroxides and Group 2 hydroxides.

Front

What is the pH formula?

Back

pH = −log [H+] and [H+] = 10^(−pH).

Front

What is the relationship between acid strength and conjugate base strength?

Back

The stronger the acid, the weaker its conjugate base.

Front

What direction do acid-base reactions favor?

Back

Acid-base reactions favor the direction from the strong side to the weak side.
