Now, let's think about what makes hydrochloric acid and sodium hydroxide - HCl and NaOH. You can thus say that in this chemical reaction, two substances react. I've been searching around the web and the consensus seems to be sodium salicylate dissolves poorly in HCl because it would form salicylic acid. National Library of Medicine. Number is an animal identifier number. And its equation reads asfollows: Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release ofheat. The optional white tile is to go under the titration flask, but white paper can be used instead. Sodium hydroselenide is a chemical compound, an inorganic salt; each unit consists of one sodium, one selenium, and one hydrogen atom. If they meet without a Chemists supervision, it bodes only disaster! Lets first visit the chemical laboratory. Continue until the solution just turns from yellow-orange to red and record the reading on the burette at this point. Example: What is the formula of the compound formed between sodium (group 1) and selenium (group 16) sodium valency = group number = 1 selenium valency = 18 - group number = 2.
