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.
SSD prices plummeted by 48 percent over the past year. The average cost of SSDs has fallen by 48 percent over the past year, with several models now falling under $1 per GB. While traditional hard drive pricing remains inflated after last year's Thai floods, the cost of SSDs continues to drop.
