The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at 1 atmosphere pressure. Units of solubility are given in grams per 100 milliliters of water (g/100ml), unless shown otherwise. The substances are listed in alphabetical order.
In general, substances have to be exposed to near boiling water for a short while to fully dissolve.
Double replacement reactions—also called double displacement, exchange, or metathesis reactions—occur when parts of two ionic compounds are exchanged, making two new compounds. The overall pattern of a double replacement reaction looks like this: \greenD{\text {A}^+\text{B}^-} + \maroonD{\text{C}^+\text{D}^-} \rightarrow \greenD{\text {A}^+}\maroonD{\text {D}^- }+ \maroonD{\text{C}^+}\greenD{\text{B}^-}A + B − +C + D − →A + D − +C + B − start color greenD, A, start superscript, plus, end superscript, B, start superscript, minus, end superscript, end color greenD, plus, start color maroonD, C, start superscript, plus, end superscript, D, start superscript, minus, end superscript, end color maroonD, right arrow, start color greenD, A, start superscript, plus, end superscript, end color greenD, start color maroonD, D, start superscript, minus, end superscript, end color maroonD, plus, start color maroonD, C, start superscript, plus, end superscript, end color maroonD, start color greenD, B, start superscript, minus, end superscript, end color greenD You can think of the reaction as swapping the cations or the anions, but not swapping both since you would end up with the same substances you started with. The solvent for a double replacement reaction is usually water, and the reactants and products are usually ionic compounds—but they can also be acids or bases. Here is an example of a double replacement reaction: \greenD{\text{BaCl}_2} (aq) +\maroonD{ \text{Na}_2 \text{SO}_4} (aq)\rightarrow \greenD{\text{Ba}}\maroonD{\text{SO}_4} (s)+ 2\maroonD{\text{Na}}\greenD{\text{Cl} }(aq)BaCl 2 (aq)+Na 2 SO 4 (aq)→BaSO 4 (s)+2NaCl(aq)

what is the solublity table?

Can you give me example reaction of double displacement?

Must we balance the equation for this for predicting the product?
BalasHapusof courses yes abi
HapusWhy a metal will replace the cation and a non metal will replace the anion?
BalasHapuswhat the different about chemical reaction and chemical equestion?
