Given:
mass of sodium acetate = 18.0 grams
volume of acetic acid = 510 ml
concentration of acetic acid = 0.160 M
Solve for the ph of the buffer:
pH = pKa + log [salt]/[acid]
pKa of acetic acid = 4.76
M of sodium acetate = 82g/mol
pH = 4.76 + log [18g/82g/mol] / [0.160M*(510/1000)]
pH = 5.19
Friedrich Wohler was working with Ammonium Cyanate and found crystals of urea in his beakers
As scientists work hard for the results, they may get biased and may sometimes come up with an answer that is based on that. In order to avoid such circumstances, scientific method is put into practice.
Explanation:
- Personal preferences can some times affect a scientific answer. That is not desirable as the experiments will be repeated by different individuals and the same results should be obtained.
- That leads to the importance of documentation of systemic observation, formation of hypothesis and the experimentation to confirm the results, which is the scientific way of coming up with the answer to a scientific problem.
- Scientific methods thus helps in bringing more credibility to findings of the scientists and can be repeated by others to obtain the same results.
it is because it reacts readily with other compounds
Elemental sodium atom contains 11 electrons. Hope this helps you!
