What is the molarity of NaOH, if 15g of NaOH is mixed with 600mL?
inn [45]
M(NaOH)=15 g

v=600 ml=0.6 l

n(NaOH)=m(NaOH)/M(NaOH)

C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]

C=15g/[40g/mol*0.6 l]=0.625 mol/l

0.625M



[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875

select all the different types of protons that will cause spin-spin splitting of each other's 1h nmr signals.
Dmitry_Shevchenko [17]

The types of proton that  will cause spin-spin splitting of each other's 1H NMR signals are the protons that are not in same chemical environment.

<h3>What are the protons that cause splitting?</h3>

The NMR spectroscopy is the acronym for the term nuclear magnetic resonance. This process could only be carried out on a nucleus that has an odd number of protons such as 1-H and C-13.

The splitting would be caused by the protons that are not in the same chemical environment as others. This implies that, the types of proton that  will cause spin-spin splitting of each other's 1H NMR signals are the protons that are not in same chemical environment.
