您好！AgCl2为白色固体；HNO3无色酸性气体；其溶液就是俗称的硝酸，为无色透明溶液；浓硝酸有时发黄，因为溶有少量NO2；至于NH4OH，你一定是想问氨水（NH3·H20），记着像我括号中那样写，你那种写法是错误的；氨水为无色透明溶液；
反应方程式可以表示为: NH3 + NaHCO3 → NH4OH + CO2 在这个反应中,氨气(NH3)和碳酸氢钠(NaHCO3)发生化学反 应,产生氨水(NH4OH)和二氧化碳(CO2)。 这个反应是一种酸碱反应。碳酸氢钠是一种碱性物质,而氨气是一 种碱性气体。当氨气溶解在水中时,它会与水分子反应,生成氨水。 而碳酸氢钠与氨气反应时,碳酸氢...

Attempts to solve the MOL etch passclean problem have included using a cold SPM, such as at temperatures less than or equal to 90° C., in combination with a standard clean solution #1 (SC-1) spray process (e.g., using a mixture of ammonium hydroxide (NH4OH), hydrogen peroxide (H2O2...

The latter method was found inefficient for separations from HNO3 solutions (pH=1.0) except supplemented with selective stripping (back-extraction with 2.0molL1 H2SO4/14.5molL1 NH4OH). While from 6.0molL1 HCl, selective stripping was adequate to quantitatively strip in turns the Mo(VI) and V(...
