\( \left. \begin{array} { l } { Al _ { 2 } ( SO _ { 4 } ) _ { 3 } + 6 KOH \Rightarrow Al ( OH ) _ { 3 } + K _ { 2 } SO _ { 4 } } \\ { Al = 2 } \end{array} \right. \)

Did you know that aluminum sulfate, the compound in your equation, has been used for centuries? In ancient Rome, it was utilized as a coagulating agent in water treatment processes, helping to purify drinking water by trapping impurities. This practice has evolved, and today aluminum sulfate is commonly used in various industries, from paper manufacturing to horticulture, as it helps to improve soil acidity. When balancing chemical equations like the one you've provided, a common mistake is forgetting to account for all elements involved—especially hydroxides in reactions involving bases. To ensure accuracy, jot down the number of each type of atom on both sides of your equation. This way, you won’t just aim for a balanced equation; you'll become a balancing superstar in no time!
