Answer:
These are the isotopes of same element. i.e. hydrogen.
Explanation:
Protium and deutrium are the isotopes of hydrogen.
Isotope:
Atoms of same elements can have different atomic mass but same atomic number . These atom of an elements are called isotopes.
Hydrogen consist of three stable isotopes protium, deutrium and tritium.
These three isotopes are represented as H¹₁ , H²₁ and H³₁ respectively.
Protium consist of one proton and one electron while deutrium consist of one proton , one neutron and one electron. The number of neutron and proton is called mass number while number of electron or proton is called atomic number. The number of proton and electron are always same.That's why protium and deutrium have same atomic number but different atomic mass because there is no neutron present in protium that's why its atomic mass is less than by one from deutrium.
Answer: the reliability will be worse
Explanation:
Suppose we used 0.5 M NaOH to titrate our vinegar sample instead of 0.1 M.
Now by using 0.5M instead of 0.1M we are increasing the concentration of NaOH,
We know that the moles used = Volume x concnetration.
so for the same no of moles, if the concentration increases, the volume decreases.
Hence it will consume less NaOH.
now Since the volume decreases, the titration volume of less number will increase the % error.
Therefore the reliability will be worse.
It is insoluble. Because one of the substances are polar and the other is non-polar.
