ied by a crackling noise. This effect is referred to as decrepitation.2 Pb(NO3)2 (s) → 2 PbO (s) + 4 NO2 (g) + O2 (g)Because of this property, lead nitrate is sometimes used in pyrotechnics such as fireworks.[4]භාවිත[සංස්කරණය]Due to the hazardous nature of lead(II) nitrate, there is a preference for using alternatives in industrial applications. In the formerly major application of lead paints, it has largely been replaced by titanium dioxide.[20] Other historical applications of lead(II) nitrate, such as in matches and fireworks, have declined or ceased as well. Current applications of lead(II) nitrate include use as a heat stabiliser in nylon and polyesters, as a coating for photothermographic paper, and in rodenticides.[7]On a laboratory scale, lead(II) nitrate provides one of two convenient and reliable sources of dinitrogen tetroxide. By carefully drying lead(II) nitrate and then heating it in a steel vessel, nitrogen dioxide is produced along with dioxygen following the de
