300
Equation of pKa

What is -log(Ka)?

300

Weaker bonds to an acidic H leads to...

1.12

300

moving down the halogen, the acids becomes...

 ...stronger because larger atoms will give weaker interactions.

300

Why is Ba(OH)2 not a strong base whereas other alkaline earth metal hydroxides are?

Ba(OH)2 is not as soluable in water as some of the other alkaline earth metal hydroxides like LiOH and NaOH.

400

Henderson-Hasselbalch Equation

What is 

400

NF3 is a weaker base than NH3 because...

What is because of the greater electronegativity of F compared to H

400

300 mL of 1.0 M HCl is added to 100 mL of 1.0 M NaOH. What is the pH of the resulting solution?
