KAl(SO4)2,硫酸铝钾,它的结晶水合物俗称明矾 Ca(ClO)2,次氯酸钙 NaSiO3,硅酸钠 FeS2,二硫化铁 Cu(OH)2CO3,碱式碳酸铜 Ca(H2PO4)2,磷酸二氢钙.
Q2 can be regarded as a colorimetric and fluorescent sensor for relay recognition of Cu2+ and H2PO4− in DMSO/H2O (8:2, v/v) HEPES buffer solutions. Moreover, sensor Q2 showed a highly sensitive and selective response towards Cu2+ and H2PO4− over other metal ions and anions. ...
摘要 本发明公开了一种基于联大茴香胺和2-羟基-1-萘甲醛的双边希夫碱类传感器分子,具有荧光团萘环结构,且萘环上有-OH,希夫碱有-C=N-结构,金属离子Cu2+易与N、O原子配位形成配合物,因而能实现对Cu2+识别。在传感器分子M和Cu2+形成的配合物中加入H2PO4-,使Cu2+和H2PO4-形成更稳定的络合物,将Cu2+...

故答案为:N2;KNO3(或NH4H2PO4等);Cu2+、SO42﹣、H2O。
第一个是FeSO4吧,读作硫酸亚铁;KAl(SO4)2读作硫酸铝钾或硫酸钾铝;Ca(ClO)2读作次氯酸钙;第四个是Na2SiO3,读作硅酸钠;FeS2一般称呼其俗名黄铁矿,学名应该叫过硫化亚铁;第六个是Cu2(OH)2CO3,读作碱式碳酸铜;Ca(H2PO4)2读作磷酸二氢钙。
Cu(OH)2中氧元素的质量分数为 16×2 64+16×2+1×2×100%≈32.7%.NH4HCO3中氧元素的质量分数为 16×3 14+1×5+12+16×3×100%≈60.8%.答:H3PO4、H2SO4、Cu(OH)2、NH4HCO3中氧元素的质量分数分别为65.3%、65.3%、32.7%、60.8%. 点评:本题难度不大,考查同学们灵活运用化学式的有关计算进行分析...
解析:SiO2+2NaOH===Na2SiO3+H2O CuSO4+BaCl2===BaSO4↓+CuCl2Ca3(PO4)2+4H3PO4===3Cu(H2PO4)2
某同学以清水、缓冲液(含NazHPCU、KH2PO4的溶液,pH=7)和血浆分别为实验材料进行实验,探究“血浆是否具有维持pH稳定的功能”,主要实验步骤如下:分别加入2
The difference methods of neutron diffraction and isotopic substitution (NDIS) were applied to the total scattering patterns of H/D substituted solutions containing three types of phosphate anion (H2PO4, HPO42, PO43). The data were used to determine the pairwise structure associated with the hydr...
