Reactions/pH
« on: December 05, 2006, 11:24:39 AM »
Which of the following statements are true for the reaction


Ca(OH)2(aq)   +   HCl(aq)   ?   




1) A Salt and Water are the products


2) This is an elmination reaction


3)  When balanced, the stoichiometric coefficient of HCl is one


4)  The pH of the resulting solution would be a value other than seven

Sorry well the equation was:

Ca(OH)2  + HCl ?

The next step I got was writing the products:

Ca(OH)2  + HCl ? H2O + CaCl2
Since it's an acid reacting with a base it must form a salt and water


Then I balanced the equation:
Ca(OH)2  + 2HCl ? 2H2O + CaCl2



Therefore I pretty much know that Salt and Water are products and that the Stoichiometric corfficient of HCl is not one.   But I don't know about the other 2 chooses.

Do you know how the reaction between acid and base is called?

The acid-base reaction is also called neutralisation reaction
