Suppose 3.50 weight per cent of aqueous solution of NaCl is sea water. What of NaCl is sea Water. What is the molality of seawater? View Solution Assertion. The pH at the end point of any acid-base titration is always 7. Reason. The aqueous solution of a salt is always neutral. ...
Is NaCl, an ionic solid, soluble or insoluble in water? Explain. Lead bromide, an insoluble salt, is put into 0.10 M hydroiodic acid solution. What is expected of its solubility? a. more soluble than in pure water b. similar solubility as in...
Is NaCl, an ionic solid, soluble or insoluble in water? Explain. Water is a polar solvent and hexane (C_6H_{14}) is a nonpolar solvent. Which of the following correctly describes the solubility of the solute in the given solvent? A. mineral oil,...
20. Write the reaction taking place when aqueous solution of NaCl is electrolysed. 相关知识点: 试题来源: 解析 When aqueous solution of NaCl is electrolysed,NaCl→Na^++Cl^-+ The reaction taking place at cathode isH^+aqle^-1/2H_2(g) The reaction taking place at anode isCI_(aq)+1/2...
To find the molarity of the solution when 117 g of NaCl is dissolved in 500 ml of aqueous solution, we can follow these steps: Step 1: Determine the mass of NaClThe mass of NaCl is given as 117 grams. Step 2: Calculate the molar mass of NaClThe molar mass of NaCl (sodium chloride...
To deliver useful biological payloads into the cytosolic space of cells, cell-penetrating peptides have to cross biological membranes. The molecular features that control or enhance this activity remain unclear. Herein, a dimeric template of the arginine
Therefore, we calculated the molar ellipticity at native, aqueous conditions and a neutral pH ((θ)deg × cm2/dmol) for Buc-VBM. It showed a strong negative molar ellipticity at 200 nm and a low negative molar ellipticity at 210–230 nm and 190 nm (Figure 3D: black line). Thus, the...
Although the function(s) of most plant nsLTPs remain unknown, in large part due to the absence of a phenotype in knock-out or knock-down mutants, several studies have shown their involvement in plant growth and development, as well as roles in plant resistance to abiotic and biotic stresses...
The proton balance equation of NaCl aqueous solution with c(NaCl) = 0.1mol/L is ( ) A.[Na+] = [Cl-] = 0.1mol/L B. [Na+] + [Cl-] = 0.1 mol/L C.[H+] = [OH-] D.[H+] + [Na+] = [OH-] + [Cl-]相关知识点: ...
An aqueous solution of sodium chloride is allowed to react with an aqueous solution of silver nitrate. Identify the solid in the balanced equation. a) \ NaCl\b) \ Ag(NO_3)_2\c) \ AgCl\d) \ NaNO_3 Write the total...
