Making a salt from an alkali. If you are using an alkali-which is a soluble base-then you need to add just enough acid to make a neutral solution (check a small sample with universal indicator paper). Warm the salt solution to evaporate the water. You get larger crystals if you evaporate the water slowly.Previous.f you are using an alkali-which is a soluble base-then you need to add just enough acid to make a neutral solution (check a small sample with universal indicator paper).

Unlocking involves the removal of carrier restrictions on the handset enabling the use of an iPhone with any compatible service provider/carrier. To software unlock an iPhone it needs to have previously been jailbroken. Do I need to jailbreak my iPhone?
No big deal, you can use a free web service called IMEI Info to check an iPhoneâs unlock status, but thereâs a catch; you have to use a Facebook account and click a âLikeâ button to actually determine if the device is locked or unlocked. If youâre OK with that, the service is extremely easy to use:ut a SIM card into the iPhone, you donât need to put any facebook, email, or G+, you just put a SIM card into the iPhone to check if itâs unlocked or not. SO easy. Use the SIM Card method. Reply.
