Temporary Hard Water. Temporary hard water is hard water that consists primarily of calcium (Ca 2 +) and bicarbonate (HCO 3-) ions.Heating causes the bicarbonate ion in temporary hard water to decompose into carbonate ion (CO 3 2-), carbon dioxide (CO 2), and water (H 2 O). The resultant carbonate ion (CO 3 2-) can then react with other ions in the .The soap penetration test can also indicate whether there are trapped air bubbles or a grainy texture seen as fluctuations in force as the probe comes into contact with air bubbles or hard particles. Figure I. Figure I A graph comparing the hardness of two different bar soap formulations tested at 20 oC. Data Set # 1: Sample A (Premium Soap)
