Hi, we have to write the balanced chemical equation showing the reaction between potassium hydroxide and chromium 3 chloride.
00:08
So first of all, we will write the formulas for potassium hydroxide and chromium 3 chloride.
00:13
The formula for potassium hydroxide is k -o -h as the medium is given equest, so we will write aq here, plus chromium 3 chloride is crcl3.
00:26
Now they react to form potassium chloride and chromium.
00:31
Hydroxide.
00:33
Chromium hydroxide is insoluble in water that is why it will appear as a precipitate.
00:40
So we will write the face of chromium hydroxide as solid and the another product is potassium chloride.
00:49
So 3k .l as there are 3 cl so we have written 3k .l here to balance it we will write 3k .oh.
00:58
Now this is the balanced equation showing this.
01:02
Now the ionic equation can be written as splitting these ionic compounds into their corresponding ions.
01:12
So there are three k plus ions, three hydroxide ions, plus chromium 3 plus plus 3 chloride ions.
01:21
Now this is a solid precipitate, this remains as it is, plus 3k plus and 3 cl minus.
01:30
The net equation is obtained by removing the spectator ions...
