2024年5月28日 · Each hydroxide ion (OH-) contains one oxygen atom, and there are 6 hydroxide ions in Ba(OH)3)2. How many oxygen atoms are in one unit of the compound Ba(OH)2? There …

2016年7月25日 · $\begingroup$ $\ce{CaOH2}$ has one calcium, one oxygen and two hydrogen atoms. $\ce{(OH)2}$ means that there are two OH groups. $\endgroup$ – MaxW Commented …

2024年12月12日 · Both are the same, $\ce{Ca(OH)2}$ turning into $\ce{CaCO3}$, however I couldn't find some straight answers in regards to their curing (carbonation) time. Some claim …

2017年1月21日 · Slaked lime is $\ce{Ca(OH)2}$ (calcium hydroxide) Lime water is just a dilute solution of calcium hydroxide. Soda lime is a mixture of about 75% calcium hydroxide, a few …

2016年12月19日 · Based on an experiment, a solution that contained $\ce{Cu^2+}$ formed a precipitate with $\ce{NaOH}$. Is this how you write the equation? $$\ce{2NaOH + Cu^{2+} -> …

2019年2月6日 · Where Φ is the ionic potential, z the charge and r the radius. If $\ce{Φ^{1/2}}$ is smaller than 2.2 the ion is considered basic, above 3.2 it's considered to be acidic. In the …

The data I have been given is Mn(OH)2's pKs=12.7, as well as the standard potential for MnO2(s)/Mn(OH)2(s), which is 1.23V, and the one of O2/H2O, which is also 1.23V; nothing …

2025年2月10日 · The relative formula mass of Mg(OH)2 can be calculated by adding the atomic masses of all the elements in the compound. The Atomic Mass of magnesium (Mg) is 24.305 …

The total moles precipitated is just the moles of $\ce{CaO}$ minus $0.02M$ since the initial number of moles of $\ce{Ca(OH)2}$ is equal to the moles of $\ce{CaO}$ taken and hence the …

2018年8月16日 · But there are also ions like $\ce{Ca(OH)+}$, and non dissociated molecules $\ce{Ca(OH)2}$. Alas these ions and molecules are rarely mentioned in usual textbooks. But …
