SODIUM HYDROXIDE 32% W/W Specific hazards Corrosive liquid. Sodium hydroxide mists or vapours will be formed. Contact with metals may form hydrogen gas which is flammable and can result in explosion. Containers of flammable liquids in the area of the fire can explode upon heating. Hazardous combustion products. Specific Heat of HCl & NaOH Solution=4.017 J/g°C. Secondly, how do you calculate specific heat capacity? The units of specific heat capacity are J/(kg °C) or equivalently J/(kg K). The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are.
