Does NaCl dissociate?
yes becAUSE THE NUMBER OF IONES CHANGE
No, water is not a good conductor. Instead of that it is an insulator. This is because water (H2O) is an ionic bond which mostly don't conduct electricity. The confusion arises since in drinking water different salts are dissolved which dissociate into ions in water which are good conductors. For instance, NaCl(common salt) dissociate into Na+ and Cl-.
Ionic compounds are the compounds with dissociate into cations and anions when dissolved in solution. For example regular table salt (NaCl) is a ionic compound when dissolved in water dissociate into Na+ and Cl- , such a solution then can conduct electricity. Pure water with no impurities (no dissolved ions) is a modest insulater. Ionic compounds are combination of a metal and a non-metal.
They are very close to each other, they both dissociate completely in solution, as they both contain the sodium cation. 36g of NaCl can dissolve in 100g of H_2_0 and 50.4g of NaCH_3_COO can dissolve in 100g of H_2_O So Sodium acetate is slightly more soluable because it also forms a weak acid with the acetate ion, creating a buffer solution, where as sodium and chlorine do not.
No, if both substances are dissolved in water, because sodium chloride spontaneously dissociates into two ions that act independently in raising the boiling point, while dissolved sucrose does not dissociate into entities smaller than molecules. Therefore, 0.1 m NaCl will raise the boiling point about twice as much as 0.1 m sucrose.
Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g But that can be misleading. NaCl does not form into molecules (and salts in general do not). If you dissolve 58.5g of NaCl into water, it will…
NaOH + HCL --> NaCl + H20 The basic equation is as follows: NaOH(aq) + HCl(aq) -----------> NaCl(aq) + H20(l) sodium hydroxide + hydrochloric acid ----> Sodium chloride + water. The molecules themselves dissociate in an equilibrium and so the ionic equation is: H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) ---------> Na+(aq) + Cl-(aq) + H2O(l). hope that helps
