If this is the case for your situation, i'd agree that their results wont be very accurate as Methyl Orange's 'transition colour' occurs at pH 3.0-to-pH 4.8 an...

Hi, i am try to neutralise hcl before pouring it down the sink - i have added NaOH - but it has gone the wrong way and has gone to ph11 - how do i bring it back to ph7 for safe disposal. thanks Hi Nic, As the solution is now basic (alkaline - anything reading above pH 7) you can add an acid, i.e. H...

Thank you Merilyn

Is there a specific part of the manual you were after? i.e. the recipes for stains, agar's, etc.
