Use the concept of hydrolysis to explain why aqueous soln of some salts are acidic basic or neutral.?
Hydrolysis occurs when water breaks apart a salt into its constituent ions, leading to an acidic, basic, or neutral solution. If the cation is a weak acid or the anion is a weak base, the solution will be acidic or basic, respectively. If both the cation and anion are strong acids or bases, the solution will be neutral.
What is the balanced chemical equation for magnesium chloride and sodium fluoride solution?
MgCl2(soln) + 2NaF(soln) ------> MgF2(s) + 2NaCl(aq)
How much 7 percent NaCl soln and 45 percent Nacl sol req'd to make 800ml 15 percent NaCl soln?
Only possible to calculate approximately (without knowing densities of all solutions) when 'percent' means 'gram per 100 ml' or 'ml per 100 ml'Solve the following equations to find V1 and V2:7% * V1 (ml) + 45% * V2 (ml) = 15% * 800 (ml)V1 (ml) + V2 (ml) = 800 (ml) [Especially this 2nd equation in an approximation]Outcome: 632 and 168 ml respectively, but this is an approximation! (due to the ignoring of volume contraction: mixing will result in LESS ml's than 800 ml, so concentration will be more than 15%)
Calculate the concentration of 98 percent sulfuric acid by mass 1.84 g ml density?
To calculate the concentration of sulfuric acid, we first need to convert the density to units of g/mL. Since the density is already given as 1.84 g/mL, for a 98% solution, we take 98% of the density to find the mass of sulfuric acid in 1 mL. This would be 1.84 g/mL * 0.98 = 1.8032 g/mL.
What salt is formed when combining RbOH HNO3?
RbOH + HNO ==> H2O + RbNO. NOTE: HNO (nitroxyl) is normally found in the gas phase. In aqueous soln., it can act as an acid to produce H+ + NO-. If the question was mean to read RbOH + HNO3, the the products would be H2O + RbNO3.

Do ionic compound's or covalent molecole's conduct electicity?
Ionic compounds conduct electricity in aqueous solution or molten state. In aq. soln. or molten state, ionic compounds dissociate to release respective ions. These ions, being electrically charged, conduct electricity.
What is the abbreviation for the word solution?
The word solution is usually abbreviated as soln. A solution refers to a homologous mixture of more than two substances.
An everyday compound made up of ions?
Salt soln.

How much sodium hydroxide has to be added to acid to form a neutral solution?
i dunno i think, 1st of all, record the pH of the soln concerned. To my opinion, sodium hydroxide is an alkali, thus, its pH is/should b more than 7. Addition of sodium hydroxide to neutralise a soln should b dne to an acidic soln, that is, pH less than 7. By mixing sodium hydroxide to an acidic soln, the pH wil bcme automatically 7 n thus wil b neutral..
44444 equals 42 how come answer?
Soln No 1: 44-[{4+4}/4]=42 Soln No 2: Dummy answer (4 x 4 + 4 - 4 + 4) =4 (1X1 + 1 - 1 + 1) =4 2 =42
What are industrial evaporators define it?
an instrument use to vaporize the all parts of solvent from soln on industrial scale.
