How to neutralize Nitric acid

To neutralize nitric acid, use any basic solution like sodium hydroxide, (NaOH), sodium carbonate (NaCO3) and Sodium bicarbonate (NaHcO3). With sodium carbonate make a saturated solution of HNO3 in a beaker , and dilute to the ratio of 1:10 and pour sodium carbonate gradually till HP of 7 is attained.

Get neutralization equipment ready

Gather all required equipment: sodium carbonate for neutralization of the acid, 1 or 2 gallon sized polyethene bucket as required, protective tools like goggles, apron, gloves, 500 ml beakers, pH Indicator strips, or other pH test technique to determine when neutralization of the acid by the base is achieved.

Obtain information about standard personal safety measures

Obtain detailed information by reading Material Data Safety Sheet (MSDS) or contact environmental Health & Safety Department Hazard Communications Section if you can’t obtain MSD. Try to conform to minimum recommended personal protection standard like working in a well ventilated environment, using gloves made of things like neoprene or polyvinyl chloride depending on MSDS instruction. Wear rubber apron, lab coat and closed-toe shoes and wear goggles together with face shield. Do not forget the need to wash hand after working with the chemicals.

Neutralize the acid

Make a saturated solution of sodium carbonate in a beaker, dilute the acid to the ratio of 1:10 and slowly add sodium carbonate till a PH of between six and nine is attained. Monitor the ph with PH meter and ph indicator. A pH near 7 is preferred to reduce the possibility of plumbing damage.
