Let V ml is taken

  $\frac{5*V+1*150}{\left(V+150\right)+0.9}=2.5$            

5V + 150 = 2.25 V + 337.5

$V=\frac{187.5}{2.75}=68.18ml$            

  $Zn+2NaOH\to N{a}_{2}Zn{O}_2+H_2\uparrow$

$\begin{array}{l}2AI+2NaOH+H_{2}O\to 2NaAl{O}_2+3H_2\uparrow \\ Sn+2NaOH+H_{2}O\to NaSn{O}_3+2H_2\uparrow \\ P_4+3NaOH+3H_{2}O\to P{H}_3\uparrow +3Na{H}_{2}P{O}_2\end{array}$

At Boyle's Temperature ; gas behaves ideally for a range of pressure.

Kiliani Fischer method is for upgradation of C-chain.

A, B and C can be precipitated by HCl as well as H₂S as their insoluble chlorides and sulphides.

(D) Sn⁺² can be precipitated by H₂S but not by HCl

$S{n}^{+2}+2HCl\to SnC{l}_2\left(soluble\right)$

DiBAL-H is electron deficient reducing agent as Burane and readily reduces electron rich sp.

$AgBr?A{g}^{+}+B{r}^{-}$                

S + 10^-7                        S

(S + 10^-7) S = 12 * 10^-14

  $\therefore S=3*10^{-7}M$          

${\kappa }_{totel}=\left[6*4*10^{-7}\right]+\left[8*3*10^{-7}\right]+\left[7*1*10^{-7}\right]$          

= 55 * 10^-7 S m^-1

The slag formed is CaSIO₃ which is lighter and has less melting point.
