Which of the following statements are true for the reaction?

Question

Ca(OH)2(aq) + HCl(aq) -->




a) Water is a product

b) When balanced the coefficient of HCl(aq) is 2

c) Only ions appear in the net ionic equation

d) OH-(aq) does not appear in the net ionic equation

e) Cl -(aq) does not appear in the net ionic equation



Examples of species are (aq) (s) (l) etc.

Answer 1

If you complete the reaction:

Ca(OH)2 + 2HCl(aq) -----> CaCl2(s) + 2H2O

The net ionic equation is:

Ca(2+) + 2OH(-) + 2H(+) + 2Cl(-) ------> CaCl2(s) + 2H2O

statements a) b) are true. c)d)e) are false.

Hope it helps!

Good luck!

Answer 2

(a) is true...the products will be CaCl2 + H2O

(b) is true also...the balanced equation is:
Ca(OH)2 + 2HCl --> 2H2O + CaCl2

(c) is true since the CaCl2 is a soluble chloride in water

(d) is false...the solution will not be basic

(e) is false since the Cl-(aq) ions are products too
