Explain that “soap scum” is a common example of a precipitate that forms when certain minerals in water react with soap molecules. Tell students that they are going to make “hard water” and see how it ...
Below is an example of a precipitation reaction. Notice the two aqueous solutions make a solid substance. \(AgNO_{3}(aq) + NaCl(aq)\rightarrow AgCl(s) + NaNO_{3}(aq)\) If state symbols are not ...
A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions, calcium ions and magnesium ions. However, if excess sodium hydroxide solution is added ...
