Italian recipes: how to make Roman dish of chicken bowels with sauce
This is an old-school recipe from Rome that some might remember their grandmother’s making, which is easy to make as long as your butcher has the right ingredients.
Ingredients 闹巧for four people: 2 kg of chicken intestine, an onion, one carrot, celery, chopped parsley, 100 grams of butter, 50 grams of parma ham chopped into cubes, five tablespoons of tomato paste, some grated pecorino.
Preparation: after leaving the chicken bowell or intestine to rest in some cold water for a few hours to become white, place in a pan and cover with cold water. Add the celery, carrot and half the onion and bring to the boil before simmering at moderate heat. Cover the pan and leave to cook until the liquid is almost entirely reduced. In a flat pan simmer the butter, parma ham and the rest 信迹of the onion. Add the bowels, leaving them to take on the flavour for a few minutes. Add the tomato paste with a bit of water and cook for another 1o minutes. Serve after 液坦键adding the parsley and pecorino.
盐的分类1.正盐:单由金属离子(包罗岩丛铵根离子)和非金属离子构成。
2、酸式盐:由金属离子(包罗铵根离子)、氢离子酸根离子和非金属离子构成。
3.碱式盐:由金属离子(包罗铵根离子)、氢氧根离子 酸根离子和非金属离子构成。
4.复盐:由差别金属离子(包罗铵根离子)和酸根离子构成。
其他分类体例
1、按酸根:
含氧酸盐:Na2SO4等
无氧酸盐:NaCl等
2.按构成:
强酸强碱盐:Na2SO4等(不水解,水溶液呈中性)
强酸弱碱盐:AlCl3等(水解,水溶液呈酸性)
强碱弱酸盐:Na2CO3等(水解,水溶液呈碱性)
弱酸弱碱盐:(NH4)2CO3等(水解,谁强成谁性)
3.按构成:
氯盐:NaCl,MgCl,CuCl2等含氯离子的盐
硫酸盐:Na2SO4,CuSO4等
硝酸盐:如NaNO3等(硝酸盐全数溶于水(初中化学阶段))
碳酸盐、氯酸盐、钠盐、钾盐
……
4.按阳离子原子量量大小:
重金属盐(重金属指的是原子量大于55的金属)
轻金属盐
5.其他:
无机盐:NH4Cl
有机盐:CH3COONa
无碘盐:non-iodized salt
精造盐:refined salt
粗盐:crude salt
竹盐:bamboo salt
井盐:well salt
池盐:lake salt
矿盐:mine salt /rock salt

碱式盐详尽 岁局阐明
电离时生成的阴离子除酸根离子外还有氢氧根离子,阳离子为金属离子(或NH4+)的盐。
酸跟碱反响时,弱碱乎枣让中的氢氧根离子部门被中和,生成的盐为碱式盐。一元碱不克不及构成碱式盐,二元碱或多元碱才有可能构成碱式盐。碱式盐的构成及性量复杂多样。碱式碳酸铜Cu2(OH)2CO3和碱式氯化镁Mg(OH)Cl等都属于碱式盐。
碱式盐是碱被酸部门中和的产品。
