Lima jenis asam HA. HB. HC. HD. HE dengan tetapan ionisasi asam (ka) berturut-turut 1,5×10^(−6);1,2×10^(−6);1,0×10^(−6);1,2×10^(−5); dan 2×10^(−5). asam yang terkuat adalah…

asam yang terkuat adalah HE.

Ayo simak pembahasa berikut agar lebih paham.

Asam lemah adalah senyawa asam yang terionisasi sebagian dalam larutannya. Semakin banyak ion yang dihasilkan, maka sifat asam semakin kuat. Harga konstanta ionisasi asam (Ka) menunjukkan perbandingan konsentrasi ion-ion yang dihasilkan terhadap konsentrasi awal asam. Semakin besar harga Ka, semakin banyak ion-ion yang dihasilkan, semakin kuat sifat asamnya.

Urutan harga Ka dari yang terkecil adalah
1,0×10^(−6) < 1,2×10^(−6) < 1,5×10^(−6) < 1,2×10^(−5) < 2×10^(−5) dengan HC < HB < HA < HD < HE.

Jadi, asam yang terkuat adalah HE.

Babies get sick more often than older children or adults because their immune systems are not fully developed and functioning at full capacity , The common cold , which is an infection of the respiratory system caused by a virus , is the most frequent malady . Doctors say that normal , healthy babies get up to about seven colds before they reach their first birthday . Another common affliction is the flu , caused by a different family of viruses , which bring on high fever , chills , fatigue , and sometimes digestive symptoms like vomiting and diarrhea , in addition to the respiratory symptoms of a cold . Another reason babies get sick so often is that they are frequently around other children , often siblings , and this exposes them to viruses and bacteria at school and daycare . Children at schools and daycare get more colds , runny noses , and earinfections than children cared for at home . However , their earlier exposure to these diseases also leads them to develop immunity earlier
