The wall will have its positive charges on the side closer to the balloon
is this true?
Yes, it is true. When a negatively charged object is held close to a neutral surface, such as a wall, the negative charges in the object will repel the negative charges in the surface and attract the positive charges in the surface. This will cause the positive charges to move to the side of the wall closer to the balloon.
