Explanation / Answer

Answer 2.

H2SO4 (aq.) + 2KOH (aq.) -----> K2SO4 (aq.) + H2O (l)

Answer 3.

Moles of glucose = 5 g/180 g/mol = 1/ 36 moles

Volume = 250 mL

Molarity = moles/volume =

= 1/36 moles / 250 mL / 1000 mL per L = 1/9 M = 0.1111 M

Answer 1.

1. Neutralization

2. Standardization

3. Titration

4. Colorless and Pink

5. End Point
