That was the aim.
But it was an untidy compromise - a desperate measure, put together in a hurry. It included the Fugitive Slave Act, which was meant to be a dramatic gesture of appeasement of the South to compensate them for not acquiring California as a slave-state. In fact, it stirred up violent resentment in the North, and caused Harriet Beecher Stowe to write 'Uncle Tom's Cabin'.
The Compromise of 1850 was an arrangement to divide slave and free states equally. It did not settle the question of slavery, however. Abolitionists in the North continued to press for the end of slavery in the US. The Compromise of 1850 was short lived however, as when Congress passed the Kansas-Nebraska Act in 1854, popular voting in territories was set to determine whether a future state would be a free one or a slave state.

In 1820, politicians debated the question of whether slavery would be legal in the western territories. The Missouri Compromise permitted slavery in the new state of Missouri and the Arkansas Territory but it was barred everywhere west and north of Missouri.
The parallel of Missouri's Southern border was the official reference-point for the new Western territories when they became states of the union. Anywhere north of that line - all the way to the Pacific - slavery was illegal.
The Missouri Compromise primarily involved the regulation of slavery in the western territories. It prohibited slavery in the former Louisiana Territory north of the parallel 36°30′ north except within the boundaries of the proposed state of Missouri.
It drew a line in the sand - anywhere North of that line, slavery would be illegal. This worked well enough, but it only applied to the territories acquired from France in the Louisiana Purchase. The vast new territories acquired from Mexico in 1847 needed a new compromise. This one did not work.
