(The questions in this issue are taken from page 5 of \"Technical Worker Training Question Bank – Soda Ash Production Operators.\" An electronic version of this book is available for download in the soda ash information sharing area: http://bbs.hcbbs.com/thread-13140-1-2.html) Fill-in-the-blank questions: 1. Trona belongs to ( ) minerals, as its main components are ( ) and ( ). 2. Natronine minerals are all ( ) water, and most of them are ( ) minerals. 3. Natronine minerals can have both ( ) crystal systems and ( ) crystal systems, and often these different systems exist simultaneously. 4. Natronine minerals undergo a strong reaction when exposed to ( ). 5. The main products of natron include ( ), ( ), ( ), ( ), ( ), ( ). 6. The common associated minerals of natron are ( ) and ( ).
1. Natron belongs to the category of (soluble salt) minerals, as its main components are (sodium carbonate) and (sodium bicarbonate). 2. All natron minerals are soluble in water, and most of them are anhydrous minerals. 3. Natronine minerals exist in both (liquid) and (solid) forms, often existing in a (solid-liquid) state simultaneously. 4. Natronine minerals undergo a vigorous reaction when exposed to (acid). 5. The main products of natural alkali include (caustic soda flakes), (double-layer alkali), (trona), (pot mouth alkali), (muddy alkali), and (oral alkali). 6. The common associated minerals of natron are (table salt) and (mirabilite).

1. Natron belongs to the category of (fusible salts) minerals, as its main components are (sodium carbonate) and (sodium bicarbonate). 2. All natron minerals are (easily soluble in) water, and most of them are minerals that do not (contain water). 3. Natron minerals exist in both (liquid) and (solid) states, and often occur in a (solid-liquid) mixture. 4. Natronine minerals react violently when exposed to (acids). 5. The main products of natural alkalis include (soda ash), (double-layer alkali), (trona), (potassium carbonate), (pasty alkali), and (oral alkali). 6. The common associated minerals of natron are (table salt) and (mirabilite).
