Balance the following equation: Al 2 ( SO 4 ) 3 + NaOH → Al ( OH ) 3 + Na 2 SO 4

The balanced equation is: Al 2 ( SO 4 ) 3 + 6 NaOH → 2 Al ( OH ) 3 + 3 Na 2 SO 4 . Aluminium sulfate react with sodium hydroxide to produce sodium aluminate, sodium sulfate and water. This is an acid-base reaction.

Balance the following equation: HNO 3 + Ca ( OH ) 2 → Ca ( NO 3 ) 2 + H 2 O

The balanced equation is: 2 HNO 3 + Ca ( OH ) 2 → Ca ( NO 3 ) 2 + 2 H 2 O . The two hydroxides ( OH - ) from calcium hydroxide, which need two H + (hence the 2 : 1 ratio with HNO 3 ) produce two H 2 O .

Balance the following equation: NaOH + H 2 SO 4 → Na 2 SO 4 + H 2 O

Balancing a chemical equation follows the law of conservation of mass which states that before and after the reaction the total mass of the reactants is equal to the total mass of the products. The balanced equation is 2 NaOH + H 2 SO 4 → Na 2 SO 4 + 2 H 2 O .

Balance the following equation: BaCl 2 + H 2 SO 4 → BaSO 4 + HCl

The balanced equation is: BaCl 2 + H 2 SO 4 → BaSO 4 + 2 HCl . Note: It is a precipitation reaction in this reaction barium ion attaches to the sulphate ion to form barium sulphate which precipitates out of solution. At the same time, the hydrogen combines with chlorine to form hydrochloric acid.
