2017年3月8日 · Another way to determine ZnCl2 is acidic is this. #ZnCl_2 + 2H_2O = Zn(OH)_2 + 2HCl# #2HCl + Zn(OH)_2# = acidic solution because of HCl is a strong acid so ZnCl2 is acidic. 6M of ZnCl2 has a pH of 3 - 4. Ksp of ZnCl2 cannot be found on the internet so i think to solve from ZnCl2 solubility in water. Solubility of ZnCl2 = #(430g)/(100ml) #

2014年3月11日 · ZnCl_2 is a Lewis acid because it can accept an electron pair from a Lewis base. A Lewis acid is a molecule that can accept an electron pair and a Lewis base is a molecule that can donate and electron pair. When a Lewis base combines with a Lewis acid an adduct is formed with a coordinate covalent bond. A zinc atom has the electron configuration …

2017年3月12日 · In this website I checked that pH of 0.1M of ZnCl2 is 4.4 I tried to solve for Ka (#H^+# = #10^-4.4#) #sqrt(0.1x) = H^+ or 10^-4.4# or #0.1x = 0.000044^2# #0.1x= 1.936E-9# #x = Ka = 1.936E-8 = \frac{1.936E-9}{0.1}# You can solve this …

2018年4月25日 · What type of reaction is Zn + 2HCl > ZnCl2 + H2? Chemistry. 1 Answer Phiri Apr 25, 2018 Single Replacement

2016年4月22日 · This is a redox reaction in which the oxidation states of the metals clearly change. Zinc metal is oxidized to Zn^(2+), whereas Cu^(2+) (as cupric chloride) is reduced to copper metal. We can write the individual redox equations: Cu^(2+) + 2e^(-)rarrCu(s) Zn(s) rarr Zn^(2+)+ 2e^(-) A zinc electrode placed in a blue solution of Cu^(2+)(aq) would rapidly acquire …
