Why is a solution of naoh which was standardized yesterday unsuitable to be used as a standard solution today?

Chemistry
1 answer:
shusha [124]3 years ago
8 0
<span> It is essential that the standard solution, in this case NaOH, must be prepared daily because a standard has to have a high percentage purity. Aside from high purity, standards should also have accurate measurements. If we will use the same standard solution, there is a great tendency for the solution to get contaminated. In turn, readings using this solution will no longer be accurate.</span>

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>
