Questions & Answers about Мы будем нагревать раствор в колбе, пока он не станет синим.
Why is there a не in пока он не станет if the English translation is 'until it becomes' and not 'until it doesn't'?
In Russian, the phrase пока не means 'until'. When talking about an action that continues up to a certain result, you use пока не followed by a perfective verb. The не does not make the sentence negative; it is just a required part of the 'until' structure.
Why use the imperfective future будем нагревать instead of the perfective нагреем?
We use the imperfective будем нагревать because the heating is a continuous, ongoing process. The sentence contrasts an ongoing action in the first half with a sudden result in the second half, which uses the perfective verb станет to show exactly when the heating will stop.
Why is the word for blue in the instrumental case (синим) instead of the nominative (синий)?
After the verb стать (to become), the resulting state or noun is put in the instrumental case. This is a standard rule in Russian to show what a subject transforms into or becomes.
Why does the second part of the sentence use он (he) when referring to a liquid solution?
The pronoun он refers back to раствор (solution). Because раствор is a masculine noun ending in a consonant, it must be replaced by the masculine pronoun он, which translates to 'it' in English when talking about inanimate objects.
