Which ion has the lower ratio of charge to volume? Explain. (g) Fe³⁺ or Fe²⁺

1 answer:

7 0

Due to having lost fewer electrons than Fe3+, Fe2+ is larger. As a result, Fe3+ has a stronger nuclear pull, which causes the atomic size to decrease. As a result, Fe2+ is bigger.

The effective distance of an ion's nucleus from which it can influence its electron cloud is known as its ionic radius. Due to the removal of one or more electrons from the equivalent atom, a cation is usually substantially smaller than the corresponding atom. Additionally, the size of the resulting positive ion will be less the more electrons are removed.

Since the residual inner shell does not reach as far into space, a cation generated by the loss of electrons may cause the outer shell to completely vanish.

A phosphate buffer solution (25.00 mL sample) used for a growth medium was titrated with 0.1000 M hydrochloric acid. The compone

AysviL [449]

Answer:

0,07448M of phosphate buffer

Explanation:

sodium monohydrogenphosphate (Na₂HP) and sodium dihydrogenphosphate (NaH₂P) react with HCl thus:

Na₂HP + HCl ⇄ NaH₂P + NaCl (1)

NaH₂P + HCl ⇄ H₃P + NaCl (2)

The first endpoint is due the reaction (1), When all phosphate buffer is as NaH₂P form, begins the second reaction. That means that the second endpoint is due the total concentration of phosphate that is obtained thus:

0,01862L of HCl× $\frac{0,1000mol}{L}$ = 1,862x10⁻³moles of HCl ≡ moles of phosphate buffer.

The concentration is:

$\frac{1,862x10^{-3}moles}{0,02500L}$ = 0,07448M of phosphate buffer

I hope it helps!
