Maybe.
A salt molecule is 1 sodium and 1 chlorine. If you measure by mass, the chlorine is about 50% heavier than the sodium, so salt is not 50/50, it’s actually closer to something like 33.3/66.7.
Another possibility is the addition of something like potassium chloride, which is similar to table salt. It obviously won’t contribute any sodium though.




That looks like Iran employing its primary piece of leverage to try to get what it wants. It’s sort of like training a dog, it does something you don’t like, you punish it with strait closure. It does what you want, you reward it with strait opening.
Iran doesn’t really have a huge amount of wiggle room, there’s only so many ways they can inflict pain on their opponents. This is one of them, so they’re using it.
I will admit it does resemble the animated shenanigans of a certain wascally wabbit.
