Boric acid dissolves in water: 1 gram in 18 mL cold water, in 4 mL boiling water, 6 mL boiling alcohol. Sigma tests B0252 at 40 g/mL, and B7660 at 1 M (62 g/mL), obtaining clear solutions. Powdered boric acid may dissolve more
slowly in water than a crystalline product, but with gentle warming will dissolve to give a clear solution.
A 1 M solution of B7660 will have a pH of 3.5-6.0 in water at 20°C. Solutions of boric acid are stable at room temperature. They can be sterile-filtered or autoclaved.
硼酸，为白色粉末状结晶或三斜轴面鳞片状光泽结晶，有滑腻手感，无臭味。溶于水、酒精、甘油、醚类及香精油中，水溶液呈弱酸性。
用途：配制缓冲液及各种硼酸盐，单倍体育种中配制各种培养基。
