Yes, It can because of the acids in the Lemon Juice.

Salty lemon juice.
Lemon juice contains citric acid. Citric acid is a weak acid that has the chemical formula of C6H8O7. It reacts with chalk, which consists of calcium carbonate (CaCO3). Whenever an acid reacts with a base, a salt and water are formed. Salts can dissolve in water (they are aqueous). Therefore, when chalk reacts with lemon juice, water and aqueous sodium citrate are formed. The sodium citrate dissolves into the water.
