Answer:

Explanation:

Moles of KOH = $10^{-2}$

Volume of water = 10 liters

Concentration of KOH is given by

$[KOH]=\dfrac{10^{-2}}{10}\\\Rightarrow [KOH]=10^{-3}\ \text{M}$

$[KOH]$ is strong base so we have the following relation

$[KOH]=[OH^{-}]=10^{-3}\ \text{M}$

$pOH=-\log [OH^{-}]=-\log10^{-3}$

$\Rightarrow pH=14-3=11$

So, pH of the solution is 11

Hyposulfite, SO22–, is a polyatomic ion that has not yet been definitively confirmed to exist. However, the VSEPR model may stil

LUCKY_DIMON [66]

Answer:

The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°

Explanation:

Hyposulphite (so₂²⁻) is polyatomic ion .

According to VSEPR model

Total elrctron pairs $=\frac{1}{2} [V+X -C+A]$

V = Valence shell electrons of central element

X = No. of monovalent surrounding atoms

C = Cationic charge

A = Anionic charge

Total electron pairs $=\frac{1}{2}[6+0-0+2]= 4$

That is two bond pairs and two lone pairs
