It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the negative terminal or lead dioxide and sulfuric acid on the positive terminal).ead(II) sulfate can be dissolved in concentrated HNO 3, HCl, H 2 SO 4 producing acidic salts or complex compounds, and in concentrated alkali giving soluble hexahydroxidoplumbate(II) [Pb(OH) 6 ] 2â complexes.
IHS is projecting SSDs with average capacity of 190GB to be priced at $110 by the end of this year, dropping to $104 for a 243GB drive by the end of next year. SSD prices will be $89 for 275GB by 2016, $73 for 310GB in 2017 and $60 for 345GB in 2018. The laptop SSD price drop will come as more people move from hard drives to SSDs, which are faster and draw less power, Zhang said.
Drop a system or laptop containing a traditional hard-disk drive, and you have a very real chance of corrupting your data. But a solid-state drive wonâtâcan'tâskip a beat. Solid-state drives aren't without disadvantages, though. For one, SSDs are much more expensive than hard drives in terms of cost per gigabyte. Good, consumer-class solid-state drives run about $0.70 to $1.00 per gigabyte, whereas hard drives cost only a few cents per gigabyte. Solid-state drives donât offer anything near the capacity of hard drives, either: The most popular SSDs have capacities of about 120GB to 256GB, with 512GB to 1TB models reserved only for those with gargantuan budgets.
