The invention relates to a bicarbonate-containing medical solution package. The package comprises a gas-permeable plastic container holding a bicarbonate-containing medical solution and a gas-impermeable plastic packaging member containing the gas-permeable plastic container. A carbon-dioxide atmosphere is established in the space between the container and packaging member. In addition, a pH indicating device is contained within the space between the container and packaging member. The pH indicating device is a gas-permeable plastic packet containing a bicarbonate-containing fluid (similar to the medical solution) and a pH indicator. The pH indicator undergoes a change in color in response to a change in pH of the fluid. Use of this package allows the easy monitoring of a change in pH and consequent aging of the medical solution due to prolonged storage or damage to the outer packaging member.
