Answer:

0.5050g of KHP were titrated

Explanation:

<em>... (molar mass = 204.22 g/mol) has one acidic hydrogen. What mass of KHP was titrated (reacted completely) by the sodium hydroxide solution?</em>

<em />

The KHP is a salt used as standard to determine concentrations of bases as NaOH solutions. The reaction that occurs is:

KHP + NaOH → KP⁻Na⁺ + H₂O

<em>Only 1 hydrogen is acidic. Only 1 hydrogen reacts with NaOH</em>

In the reaction you can see that 1 mole of NaOH reacts per mole of KHP

To find mass of KHP we need to determine its moles finding moles of NaOH (The moles of KHP required to reach endpoint = Moles of NaOH added):

<em>Moles NaOH:</em>

21.30mL = 0.02130L * (0.1161mol / L) = 0.002473 moles of NaOH = Moles KPH

With mass of KHP and its molar mass we can solve the mass of KHP:

0.002473 moles of KHP * (204.22g/mol) =

<h3>0.5050g of KHP were titrated</h3>

musickatia [10]

Answer:

This is the balanced equation:

Pb(NO₃)₂ (aq) + 2NaI (aq) → 2NaNO₃ (aq)  +  PbI₂ (s) ↓    

Explanation:

This are the reactants:

PbNO₃

NaI

Iodide can react to Pb²⁺ to make a solid compound.

By itself, i don’t think so.

though, paired with a hydrogen bond, it is.

If i’m wrong, please feel free to let me know :)
