Sodium chloride, carbon dioxide, and water are formed when sodium carbonate interacts with hydrochloric acid. Allowing carbon dioxide gas to travel through lime water turns it milky.<\/p>\n\n\n\n<p>Acid&nbsp;+ metal carbonate&nbsp;or bicarbonate&nbsp;\u2192&nbsp; salt + water + carbon dioxide.<\/p>\n\n\n\n<p>2HCl + CaCO<sub>3&nbsp;<\/sub>\u2192 CaCl<sub>2&nbsp;<\/sub>+ H<sub>2<\/sub>O + CO<sub>2<\/sub><br>H<sub>2<\/sub>SO<sub>4&nbsp;<\/sub>+ Mg (HCO<sub>3<\/sub>)<sub>2&nbsp;<\/sub>\u2192 MgSO<sub>4&nbsp;<\/sub>+ 2H<sub>2<\/sub>O + 2CO<sub>2<\/sub><\/p>\n\n\n\n<p>Effervescence indicates liberation of CO<sub>2<\/sub>&nbsp;gas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">c)&nbsp;Reaction of Acid with Base<\/h3>\n\n\n\n<p>1.

Reaction of acids and base<\/p>\n\n\n\n<p>A very common acid is hydrochloric acid. The reaction between strong acid says hydrochloric acid and strong base say sodium hydroxide forms salt and water.
