Potassium hydrogen phthalate, KHP, is used as a primary standard for determining the concentration of a solution of NaOH by titr

ation. If the KHP has not been dried before weighing, the calculated molarity of the NaOH would be
A) higher than the actual value, since water is included in the apparent mass of KHP

B) higher than the actual value, since the presence of water requires a larger volume of titrant

C) lower than the actual value, since NaOH absorbs water

D) unaffected, since KHP is a strong acid

E) unaffected, since water is routinely added before the titration

What is the new freezing point for a 0.811m solution of Li2O in water?
rewona [7]

Answer:

Freezing T° of solution = - 4.52°C

Explanation:

ΔT = Kf . m . i

That's the formula for colligative property about freezing point depression.

Li₂O is an oxide that can not be dissociated but, if we see it's a ionic compound.

Li₂O →  2Li⁺  +  O⁻²

3 moles of ions have been formed. Ions dissolved in solution are i, what we call Van't Hoff factor.

m is molality → 0.811 m, this is data

Kf →Cryoscopic constant, for water is 1.86 °C/m

and ΔT = Freezing T° of pure solvent - Freezing T° of solution

We replace: 0°C - Freezing T° of solution = 1.86°C/m . 0.811 m . 3

Freezing T° of solution = - 4.52°C

Sodium is more reactive than lithium, despite both belonging to group 1. Explain why
kari74 [83]
In group 1, elements get more reactive going down the group. Sodium is more reactive than lithium since when going down, each element gains an extra valence electron, and the outer shell electrons get further and further away from the nucleus while also becoming more in number. Due to this, the element becomes unstable and more reactive.
