Sifat larutan elektrolit pada senyawa ionic Senyawa ionic yang dilarutkan dalam air ion-ionnya akan bergerak bebas. 4 Reaksi ionisasi senyawa Ionik: ▪KBr(aq)  K + (aq) + Br – (aq) ▪CaCl 2 (aq)  Ca 2+ (aq) + 2Cl – (aq)

Reaksi ionisasi: HCl(l) + H 2 O(l)  H 3 O + (aq) + Cl – (aq) HCl(aq)  H + (aq) + Cl – (aq) NH 3 (l) + H 2 O(l) ↔ NH 4 + (aq) + OH – (aq) Sifat elektrolit pada senyawa kovalen Kovalen Polar Senyawa kovalen polar yang murni merupakan penghantar listrik yang buruk, tetapi jika dilarutkan dalam air makan akan menghasilkan larutan yang menghantarkan arus listrik. 5 Kovalen non Polar Tidak terionisasi Tidak menghantarkan arus listrik

JENIS LARUTAN SIFAT DAN PENGAMATAN CONTOH SENYAWA REAKSI IONISASI Elektrolit Kuat - terionisasi sempurna - menghantarkan arus listrik - lampu menyala terang - terdapat gelembung gas NaCl, HCl, NaOH, H 2 SO 4, dan KCl NaCl  Na + + Cl - NaOH  Na + + OH - H 2 SO 4  2H + + SO 4 - KCl  K + + Cl - Elektrolit Lemah - terionisasi sebagian - menghantarkan arus listrik - lampu menyala redup - terdapat gelembung gas sedikit CH 3 COOH, NH 4 OH, HCN, dan Al(OH) 3 CH 3 COOH  H + + CH 3 COO - HCN  H + + CN - Al(OH) 3  Al OH - Non Elektrolit - tidak terionisasi - tidak menghantarkan arus listrik - lampu tidak menyala - tidak terdapat gelembunggas C 6 H 12 O 6, C 12 H 22 O 11, CO(NH 2 ) 2, dan C 2 H 5 OH C 6 H 12 O 6 C 12 H 22 O 11 CO(NH 2 ) 2 C 2 H 5 OH

, kovalen polar dan nonpolar. You can also split your content White Is the color of milk and fresh snow, the color produced by the combination of all the colors of the visible spectrum. 12 Black Is the color of coal, ebony, and of outer space. It is the darkest color, the result of the absence of or complete absorption of light.

BIG CONCEPT Bring the attention of your audience over a key concept using icons or illustrations 13

In two or three columns Yellow Is the color of gold, butter and ripe lemons. In the spectrum of visible light, yellow is found between green and orange. According to surveys in Europe, Canada, and the United States, yellow is the color people most often associate with amusement, gentleness, and spontaneity, but also with duplicity, envy, jealousy, avarice, and, in the U.S., with cowardice. It plays an important role in Asian culture, particularly in China, where it is seen as the color of happiness, glory, wisdom, harmony, and culture. Blue Is the colour of the clear sky and the deep sea. It is located between violet and green on the optical spectrum. Surveys in the US and Europe show that blue is the colour most commonly associated with harmony, faithfulness, confidence, distance, infinity, the imagination, cold, and sometimes with sadness. In US and European public opinion polls it is the most popular colour, chosen by almost half of both men and women as their favourite colour. Red Is the color of blood, and because of this it has historically been associated with sacrifice, danger and courage. Modern surveys in the United States and Europe show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love and joy. Red is also a color widely used for getting attention, such as stop signs or royal dresses. In China, India and many other Asian countries it is the color of symbolizing happiness and good fortune. 14

It provides a familiar way to convey information that might otherwise not be obvious or readily understood.
