Question 5: Which of these substances is likely to form a precipitate?Įxplanation: Bromides are usually soluble but salts of silver are mostly insoluble. Rest of the mentioned salts have exceptions. Question 4: Which of the following are always soluble in water?Įxplanation: Salts containing Group 1 elements also known as alkali metals (Li+, Na+, K+, Cs+, Rb+) are soluble in water. Silver - Ag+ A - Ammonium NH 4 + G - Group 17A metals -> Exceptions: Castro Bear Ca+2, Sr+2, Ba+2. Question 3: Which of the following salt is slightly soluble in water?Įxplanation: Most hydroxides are insoluble in water, But some like calcium hydroxide and barium hydroxide are slightly soluble. 'Castro Bear' mungkin terdengar aneh, tetapi itu mewakili ion kalsium (Ca), strontium (Sr) dan barium (Ba). Hafalkan 'Castro Bear' sebagai pengecualian kedua. Nitrates, sulfates, halides all are mostly soluble in water. Saat Anda menulis aturan mnemonik, letakkan tanda bintang di sebelah PMS dan tanda bintang serupa lainnya di sebelah S dan G dari SAG untuk mengingat bahwa ini adalah pengecualian. Question 2: Which one of the following salts are mostly insoluble in water?Įxplanation: Carbonates are frequently insoluble in water. Na2So4, CuSO4, MgSO4 are all soluble in water. Question 1: Based on the solubility rules, which one of the following compounds should be insoluble in water?Įxplanation: Among the given options, BaSO4 insoluble in water. (d) represents decomposition (complex reactions) Solubility rules are sets of rules predicting the solubility combinations of different cations and anions and on mixing with each other.
