I need help with my Chemistry homework. Can anyone help?
I need to describe the reactions for:
Potassium Carbonate and Hydrochloric acid
Zinc Chloride and Silver Nitrate
Magnesium Chloride and Sodium hydroxide
Ammonium Nitrate and Sodium hydroxide
I need to have the physical descriptions, like cloudy or turns color or no reaction. I have no idea on any of them. It's insane. If you can help, PLEASE DO! I can't work with the chemicals, we're just supposed to know/assume what happens, but I've got no clue.
I'm on until like 10:30 EST. After that, it'll be too late. ;-;
And of course, my teacher had a soccer game, so I can't IM or ask him via facebook.
So I'm asking you guys. <3

K wait... so what you need is like what? The formulas?

buzzkid24 K wait... so what you need is like what? The formulas? Not the formulas, the reactions that take place. Like, the physical observances. Like, if you mix them, the solution turns cloudy or changes color.

Imma look for answers. On the webz. This might take time.
This is what I found for potassium carbonate and hydrochloric acid.Quote: Potassium carbonate will react with HCl to produce potassium chloride, water and carbon dioxide. The balanced equation is as follows: K2CO3 + 2HCl --> 2KCl + H2O + CO2 The closest I could find for a magnesium chloride and sodium hydroxide is this (the equation is there, too):Quote: A method for controlling both fugitive bauxite dust and sodium hydroxide contamination generated by the waste disposal of bauxite tailings from aluminum processing plants comprising using magnesium chloride or sodium chloride or mixtures thereof on the surface of the disposal pits, which are also known as mud lakes. Preferably, a solution of magnesium chloride is applied to the surface of a dry or partially dry mud lake. The magnesium chloride neutralizes the sodium hydroxide on the surface, forms a hard crust that covers the fine bauxite particles and also inhibits the migration of unreacted sodium hydroxide to the surface. MgCl2 + 2NaOH = 2NaCl + Mg(OH)2 Ammonium nitrate and sodium hydroxide, or the closest I could find to an answer:Quote: NH4NO3 + NaOH ------> NH3 + H20 + NaNO3 -Smell of ammonia. -Colourless gas.

OHHH!!!! I remember doing that in class. But I can't for the life of me remember that happens... sorry... >.<

I feel stupid. ;-; @Luna - I don't need equations so much as observable reactions. Equations are so much easier to find. It makes me sad. ;-;

I edited the post, look again. I'll try to look in Spanish afterwards, if I have time, the more possibilities, the better.

It's been WAY too long for me to do anything but equation balancing at this point... and that's not what you need...
._.( )
I will say this, that I'd be surprised if any of the reactions didn't generate heat in some way, shape, or form... then again, it's not like you find many reactions that aren't exothermic, right?
That, and look in your chem book, the LOVE to throw in pictures of reactions (look in the complex ions section?) with these things... that might help.
but yeah, I'm no help here, unfortunately, as I don't have this stuff memorized...
._.( )

Lady Rai Luna Amatista I edited the post, look again. I'll try to look in Spanish afterwards, if I have time, the more possibilities, the better. Merci! Unfortunately, that's all I could find (I searched in Spanish, too). Well, all the answers I got are now in my first post in the thread. Hope they can help any...

My textbook is like "Reactions? You want to know what they look like? Silly girl. 8D" @Luna - Thanks for those, though. That's 2 that I didn't have. Ughhh, I'm going to go to bed. Hopefully someone knows tomorrow before class. >>;

let's see if i remember anything from gen chem. xD
well, you could try writing the balanced equations and seeing if you end up with any solids in the product. that'll tell you if you get a precipitate, which can turn the solution cloudy.
because i feel like it (and because this is more interesting than reading john steinbeck) i'ma try to demonstrate what i'm talking about.
potassium carbonate: K2CO3 hydrochloric acid: HCl
soooo
K2CO3(aq) + 2HCl(aq) ---> 2KCl(aq) + H2CO3(aq)
so it shouldn't turn cloudy since everything is soluble in water (i believe - i might be wrong).
also wtf @ the color thing. that's just weird. o-O

K+ is either purple, or yellow... I forget... but nothing there should be red... If it had some iron, maybe, but... that's odd... o.o
