The β value is the ratio of the concentrations of ( ) and ( ) in ammonia II. 2. The founder of my country’s joint alkali production method is ( ). 3. The crystallization process is divided into three processes: ( ), ( ), and ( ). 4. The degree of carbonation refers to the degree of solution ( ), generally expressed by the neutralization percentage of ( ) to ( ).
1. The β value is the ratio of the concentration of (free ammonia) to (sodium chloride) in ammonia II. 2. The founder of my country’s joint alkali production method is (Hou Debang). 3. The crystallization process is divided into three processes: (formation of saturated solution), (generation of crystal nuclei), and (growth of crystals). 4. Carbonation degree refers to the degree of solution (carbonation), generally expressed by the neutralization percentage of (carbon dioxide) to (ammonia).
