I can't believe that Professor Dave explained at 1:34 what I'd been trying to figure out for days in two seconds. If my teacher had just explained it instead of technically speaking a different language, it would be SO much easier. But as my teacher can't explain it very well, Professor Dave is a lifesaver. Thank you, Professor Dave!!!!!!!!

Wow! We are doing ionic compounds now. And, of course, covalent compounds, too. I'm not sure if you are working on (or getting ready to) a video about covalent compounds yet, but that'd be great. I have a pretty solid instructor (first ever chemistry class at the age of 24 in college), but... I get lost in the transition despite paying attention the best of my abilities. You are the man, PD. Thanks for everything and keep up the great work.

[@gabriels2395]

Hello professor Dave! As always let me start by thanking you because your videos help me a lot! This time I don't get why in 3:44 you say that *S* has an oxidation number of -2. If so, what oxidation number does the *O* have here? Thank you again!!

[@ProfessorDaveExplains]

so not the sulfur atom, but the sulfate as a whole! we know that SO4 2- is the sulfate ion, so the whole thing has to add up to -2, and 4 O's add up to -8 so sulfur is +6.

[@gabriels2395]

Oh I see!!! Of course! Thank you professor Dave!

[@kgamesekoto7221]

Well presented Prof👌

[@savannawilson8917]

Hes great!! Ive even checked to see if he has videos on nursing lol

[@keithstaana9637]

hi professor dave. i just want to ask if the subscripts we place below cations and anions (sometimes enclosed in a parentheses) to make their charges neutral affects their over-all molar mass. thank you very much

[@ProfessorDaveExplains]

yes definitely! if there is a subscript indicating two sulfate ions, then the mass must take into account both of those sulfate ions.

[@keithstaana9637]

so for example, the iron (II) phosphate in 4:04 where in the phosphate has a subscript of 2 means the phosphate must have 2 moles, thus making their molar mass doubled?

[@ProfessorDaveExplains]

it means that there are two phosphate ions per formula unit of the salt, so when calculating the formula mass, you need two phosphates, and so two phosphorus atoms, and eight oxygen atoms.

Sir, if oxygen has one bond and three lone pairs, as in hydroxide ion, it will have a formal charge of-1. From where does this one additional charge or one extra electron come? Also in the case of carbonate ion two of the oxygen atoms are single covalently bonded, so if oxygen has 6 valance electrons and it is sharing its one electron in bond formation then how does the lone pair upon bond formation of oxygen atom count upto three I mean since it has to share one of its six electrons in the bond, shouldn't it have 5 electrons. How after forming a single bond this one additional electron comes from here so that it provides the atom with a negative charge?

Copper has an electron configuration of [Ar] 3d10 4s1 (sorry I don't know how to make superscripts) Cu+ has lost the electron that was in the 4s orbital, giving a configuration of [Ar] 3d10. Cu 2+ has the configuration [Ar] 3d9. Cu 7+ does not occur.
