All my students, the following is my suggestion for you in learning chemistry. For this moment, I focus on the topic of acid and base solution.
1. To learn acid and base theories, please make a comparison among the three theories, find the similarities and differences.
2. Be careful with the Bronsted-Lowry's theory, if the acid is weak, so the conjugate base is strong. A lot of particles can be acted as both acid and base in the different reaction (amphiprotic)
3. To calculate the concentration of acid or base, weak or strong one, please think about the degree of ionization. If there is a known Ka or Kb, please think about the weak acid and weak base.
4. To determine the value of pH, please calculate first the concentration of hydrogen/hydroxide ions.
5. Remember that there are so many variation in calculating the concentration of acid or base, and also the value of pH.

bu etna..
ide bagus bu..
saya jadi terbantu ada blog ini..
sekalian bisa nambah wawasan tentang kimia
makasih ya bu ^,^
bagus banget bu isi blognya
semangat ini mampu membuat saya untuk lebih semangat belajar kimia..
saya dulu menganggap kimia so hard
tapi sekarang saya selalu ingat2 kata2 bu etna
"chemistry so easy"
thank's my lovely teacher for your support to me...^_^
kunjungi blog saya ya bu...
tapi maaf kalo jelek?
:P
bu, mw tanya, ne...
sebenarnya derajat ionisasi itu apa to?pengertiannya?
trus kenapa rekasi penggaraman asam kuat dan basa kuat menghasilkan pH =7?
itu perhitungan rumuse gimana?penjelasan sedetail2nya gimana, bu?
tolong, ya bu?
terima kasih...
bu, sebenere derajad ionisasi itu apa c?
trus, kenapa rekasi penggaraman asm n basa kuat menghasilkan pH 7?
hitungane gimana itu bu?
tolong, y bu...
terima kasih..
