A chemical reaction takes place between substances such as strontium chloride salt and sodium sulfate salt. After the reaction proceeds, a sodium chloride salt and a strontium sulfate salt are formed, which precipitate.
SrCl2 + Na2SO4 = 2 NaCl + SrSO4 ↓
Sr2 + + SO42- = SrSO4
2. The reaction takes place between substances such as sodium hydroxide and hydrochloric acid. As a result of a chemical reaction, water and sodium chloride salt are formed.
2 NaОН + НCl = H2O + NaCl
2 Na + + OH – + H + + Cl – = Na + + Cl – + H2O
OH – + H+ = H2O.
