1M sodium hydroxide

1M sodium hydroxide sodium hydroxide TS里的 1.0 N sodium hydroxide solution 啥意思?5mBoil 0.5 g of the powdered tablets for 2 to 3 minutes with 10 ml of 5M sodium hydroxide,cool and add an excess of 1M sulphuric acid; a crystalline precipitate is produced.那个5m sodium hydroxide Sodium hydroxide这是什么化物 Ammonium chloride + Sodium hydroxide → Sodium chloride + ammonia Ammonium chloride + Sodium hydroxide → Sodium chloride + ammonia 的化学式是什么啊 知道的就快来帮个忙啊!回答满意在给分（20） 英语翻译Dissolve 0.250 g in 50 mL of alcohol R and add 5.0 mL of0.01 M hydrochloric acid.Carry out a potentiometric titration(2.2.20),using 0.1 M sodium hydroxide.Read the volumeadded between the 2 points of inflexion. sodium hydroxide和 acrylic acid 合在一起会产生什么化学成份 Sodium hydroxide 和 acrylic acid在一起会起什么化学反应要求提供反应后的化合物化学成分名称,CAS# 英语翻译This compound was prepared hydrothermally from mixtures of titanium tetraisopropoxide,tetraethylorthosilicate,and 6–10 M sodium hydroxide.Temperatures ranging from 170 to 200 °C were used for 3–7 day’s time.The solid had a range of 英语翻译1.Reagents:The chemicals used in this work were,ammonium molybdate,diammonium monohy-drogen phosphate,ascorbic acid,ammonium metavanadate,.zine powder and sodium hydroxide,etc.All of these reagents were analytical grade and doubly distill Nitric acid R 中的 R 谢谢楼下的回答，不过还有的是溶液后面写R啊，那又是怎么回事呢？比如：Potassium dichromate solution R,dilute Sodium Hydroxide solution R,Ferric Chloride Solution R1之类的，对了， 英语翻译4) desulphurization5) hazard warning label 6) hydrochloric acid 7) litmus paper8) nitric acid 9) nitrogen oxides 10) pH paper 11) pH scale 12) sodium hydroxide 13) sulphur dioxide14) sulphuric acid 15) universal indicator 英语翻译Davis et al.(2000) stated that,when the concentration of sodium hydroxide is less than 50 wt.%,from ambient temperature to 95 ℃ carbon steel could be used. 化学英语译成中文,是关于手性拆分的,万分紧急,Selective Extraction of d-mene with d-Tartaric Acid:amines were resolved with 0.5 mole tartaric acid in benzene-water containing 0.5 mole sodium hydroxide or potassium hydroxide by select metal hydroxide是什么意思 Hydroxide是什么意思?如题 外贸英语中 1 *20 of sodium bicarbonate是什么意思
