Which of the following substances can sodium hydroxide react with: a) HCl b) LiOH c) NaCl

Which of the following substances can sodium hydroxide react with: a) HCl b) LiOH c) NaCl d) BaO e) H3PO4 f) CO2 Write the equations of possible reactions.

Of all the listed substances, sodium hydroxide will react only with substances under the letters a, e and e:

NaOH + HCl = NaCl + H2O;

3NaOH + H3PO4 = Na3PO4 + 3H2O;

2NaOH + CO2 = Na2CO3 + H2O;
