此后,以 30 分钟~2 小时的间隔时间监测血 pH,直到上升至 7.0 以上才停止补碱[17]。 过多过快补碱不利影响: 1. 二氧化碳透过血脑屏障的弥散能力快于碳酸氢钠快速补碱后脑脊液 pH 呈反常性降低,引起脑细胞酸中毒,加重昏迷; 2. 血 pH 骤然升高...

植物激素主要包括生长素（Auxin，AUX）、乙烯（Ethylene，ETH）、细胞分裂素（Cytokinin，CK)、脱落酸（Abscisic acid，ABA）、赤霉素（Gibberellin，GA）、油菜素甾醇（Brassinosteroids，BRs）、茉莉素（Jasmonate，JA）、独脚金内酯（Strigolactones，SLs）、水杨酸（Salicylic acid，SA）、褪黑素（Melatonin，MT）和多肽...
Calculating the pH of a base is the same as for the acid mentioned above. The only difference is when you don't find the base of your choice in the list of options and you choose to enter a custom base, you will enter the ionization constant (Kb) of a base instead of Ka. The to...
百度试题 结果1 题目Acid-base indicators (also known as pH indicators) are substances which change color with pH.相关知识点: 试题来源: 解析 酸碱指示剂,又称pH指示剂,是颜色随pH而变化的物质。反馈 收藏

● 2024年1月8日,华北理工大学宋小明团队在iMeta在线联合发表了题为 “PHGD: An Integrative and User-friendly Database for Plant Hormone Related Genes” 的研究文章。 ● 本文收集了模式植物拟南芥中所有已报道的激素相关基因,绘制了激素基因相互作用网络图,建立了PHGD平台网站(phgd.bio2db.com/),包括主页...
Lemon juice is an acid with a pH of 2, while baking soda is an alkali with a pH of about 9.5.(檸檬汁是 pH 值 2 的酸,小蘇打則是 pH 值大約 9.5 的鹼。) 那標示 pH 值的量表就稱為pH scale,簡單幫大家複習一下,pH 值 7 是中性,小於 7 就是酸性,大於 7 就是鹼性喔!可以參考下面這...
pH range vs. color change for acid and base indicators - together with pKa and structures of the indicators.
An acid is a substance that increases the concentration of hydrogen ions (H+) in a solution, usually by having one of its hydrogen atoms dissociate. A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in ...
