Which aqueous solution will have the highest boiling point temperature? A. 0.100 molal NiBr2(aq) B. 0.250 molal CH3OH(aq) C. 0.1
zaharov [31]

Answer: 0.150 m Na_2SO_4(aq) will have highest boiling point.

Explanation:

Formula used for Elevation in boiling point :

\Delta T_b=i\times k_b\times m

where

\Delta T_b=T_b-T^o_b= elevation in boiling point

[tex[k_b[/tex]  = boiling point constant  

m = molality

i = Van't Hoff factor

A) 0.100 m NiBr_2

i = 3 as NiBr_2\rightarrrow Ni^{2+}+2Br^-

concentration will be 3\times 0.100=0.300

B) 0.250 m CH_3OH

i = 1 as CH_3OH is a non electrolyte

concentration will be 1\times 0.250=0.250

C) 0.100 molal MgSO_4(aq)

i = 2 as MgSO_4\rightarrrow Mg^{2+}+SO_4^{2-}

concentration will be 2\times 0.100=0.200

D. 0.150 molal Na_2SO_4(aq)

i = 3 as Na_2SO_4\rightarrrow 2Na^{+}+SO_4^{2-}

concentration will be 3\times 0.150=0.450

E. 0.150 molal NH_4NO_3(aq)

i = 2 as NH_4NO_3\rightarrrow NH_4^{+}+NO_3^{-}

concentration will be 2\times 0.150=0.300

The solution having the highest concentration of ions will have the highest boiling point and thus 0.150 m Na_2SO_4(aq) will have highest boiling point.

What is the pH of a solution with a (H+] = 0.80 M? *Please round your answer to the appropriate number of significant figures. Y
bezimeni [28]

Answer:

The pH of a solution with a (H+] = 0.80 M is 9.6 e^{-2}

Explanation:

As we know

pH = -[log H+]

Substituting the value of H+ ion concentration in the above equation, we get -

pH = -log [0.80]

pH = -[-0.096] = 0.096  = 9.6 e^{-2}
